Emissions trading offers a market-based approach to achieve environmental policy goals by providing financial incentives to reduce emissions and other pollutants.

The central emissions trading mechanism is known as cap-and-trade. Under such a program, a government or other authority establishes a total limit - known as the cap - on the targeted pollutant based on a prior emissions year. Emitters are given an emissions target, generally on an annual basis, which they are required to meet.

Using both carrots and sticks, cap-and-trade typically includes a penalty structure in the event of non-compliance. Emitters that need allowances can make up for the shortfall by buying permits from other allowance holders who have a surplus. However, the total cap on how much can be emitted annually stays constant, ensuring that while some emitters may increase emissions, society benefits through an annual reduction in the overall level of emissions covered by the program.

In addition to domestic reductions, an emissions trading program may also permit the use of so-called offset permits. The Clean Development Mechanism CDM is currently the largest offset market and encourages the transfer of clean energy technologies by implementing emissions reduction projects in developing countries. At the same time it allows the developed world to finance the required emissions reductions at a lower cost as it is generally cheaper to abate greenhouse gas emissions in the developing world.

These include power stations, combustion plants, oil refineries and iron and steel works, as well as factories making cement, glass, lime, bricks, ceramics, pulp, paper and board. By linking to the Kyoto Protocol, the EU ETS allows companies to use international offset credits to meet part of their compliance target. In addition, the EU ETS will expand its current scope by including petrochemicals, ammonia and aluminium industries and two additional greenhouse gases nitrous oxide and perfluorocarbons in the program from Airlines will also be subject to compliance requirements beginning in Since carbon trading took off in Europe, trading volumes and underlying asset values have grown beyond expectations.

If the costs of climate protection [ 1 ] are offset against the benefits of economic growth, the difference is about one year of delayed economic growth for Europe by The level of prosperity that is forecast for would thus be reached in when the costs of climate protection are factored in.

But this does not yet take into account the costs of damages caused by climate change that would be averted. Unless we act in the coming decade, RECIPE Report on Energy and Climate Policy in Europe predicts that not only will the costs of reducing global CO 2 levels rise, but the chances of still being able to stop the dangerous consequences of climate change will fall dramatically.

After , the window for ambitious climate protection will close entirely. To help guide government leaders at the climate talks in Copenhagen, RECIPE is calculating possible cost distribution models for climate protection in six regions of the world. The findings make it clear that effective climate protection at low costs is achievable only if we act without delay. Concrete paths toward reducing CO 2 in these regions are designed to provide a stable environment in which appropriate incentives will quickly develop - not only for the necessary investments in new technologies but also for research and transfers to emerging countries.

A cost-optimal mitigation strategy for the transformation of the energy sector alone requires an increase of investments in low-emission technologies to an annual level of to 1, billion by , most of which would have to be provided by the financial markets and industry. It is now up to governments to provide these conditions. This includes not only reliable paths toward reduction targets but market-based economic elements such as the auctioning of all CO 2 certificates, the establishment of global cap and trade systems, rapid implementation of the EU Directive to promote renewable energies that guarantees investors reliable feed-in tariffs, and stronger subsidies for research into low carbon technologies.

The latest scientific findings suggest that to achieve a high probability of limiting the rise in global temperature to 2 C, additional emissions until must be held below GtCO 2 [ GtC]. Too often, energy debates descend to energy-bashing, with heated rhetoric instead of analysis. The Coalition for Energy Solutions is a group of energy professionals dedicated to understanding various energy scenarios, and presenting the feasibility, basic environmental effects, and costs in a clear and objective fashion. In , Germany's power production was The German experience shows the economics of utility-size wind and PV solar power are such that utility-size wind provides about 6 times the power of PV solar for less than one third the subsidies spent on PV solar.

Nations with high wind power production are. The following is probably an example of misleading data: given is a snapshot in time that does not reflect the smoothed situation as do the numbers for Spain, Portugal and Denmark above. In recent years, Ireland has aggressively developed wind power generation projects.

As Ireland has expanded their variable wind generation capabilities, they have learned that this type of power adds a layer of complexity to the operation of the power grid that was not present in earlier times. As it turns out, the ability to reliably operate the grid with large portions of variable wind power is a key constraint. The minister maintains that these investments are so difficult to swallow, because they are not glamorous or high profile in nature. In the future, Ireland will forge ahead with plans to continue to expand it wind generation capabilities.

Continued expansion will bring along new challenges. This means that Ireland will need to build an interconnection with one or more neighboring electrical grids. The minister shared that there has been a change in thinking among the EU's Council of Ministers in the last three years. He feels as though the EU now understands that it needs to build an interconnected grid. He spoke of the interconnection plans that are now being drawn up at the EU Council of Ministers level. In the coming years, Mr.

Ryan believes that the EU will approve and build an interconnected grid. Spain and Portugal are also using quick-responding combined cycle gas turbine , CCGT , plants to smooth their wind power. Other power plants are in standby mode; they usually are started each day to provide power during peak demand periods. Portugal's power production is from. Pumped storage hydro plants tied in with wind farms is by far the lowest cost renewable power arrangement, as proven by Denmark, Spain and Portugal during the past 10 years. Germany's power plant capacity is about GW.

Germany's electric power grid is strongly connected to nearby grids. It is designed as they do their cars, etc. As a result Germany can handle 6. Germany has insufficient hydro plants and relies mostly on CCGT plants and a well-designed electric power grid to smooth its wind power. Energy planning in response to climate change: Accurate costs are critical. Synapse conducts energy planning and policy analyses for a wide range of clients, including agencies of the US government, states, non-governmental organizations, and others.

Synapse's recent projects include an analysis PDF for the Civil Society Institute of the benefits of transforming the electric power industry by ; the study uses cost data from recent projects wherever possible, and includes the costs of integrating large amounts of variable generation into the US power system, as well as the costs of new transmission needed to deliver renewable energy. A step in the right direction. Responding to these and other data, the US Energy Information Administration EIA has in the last year revised its assumed costs of new nuclear power plants , placing more emphasis on data from actual projects.

This is a move in the right direction, but cost forecasts should be revisited frequently to ensure that they reflect the latest data and trends. Moreover, it is important to consider the effects of subsidies when costing out various technologies for a study designed to inform long-term energy policy. Consumers pay the full cost of any new resource, whether they pay this cost through electricity rates or through their tax dollars. We need to do careful and current research on all resource types -- not just nuclear.

But the cost of new wind began trending up again in the late s and has remained well above the lows of the last decade. The most economical new wind projects today are coming in at 7 cents to 8 cents per kilowatt-hour. Photovoltaics , on the other hand, have seen dramatic cost reductions since mid Again, focusing on real market data:. All of these photovoltaic prices include a federal subsidy , so actual project costs are likely to be 3 cents to 4 cents per kilowatt-hour higher. But clearly photovoltaic costs have reached a major inflection point, and it will be crucial to stay abreast of these costs over the next several years and to rely on current data.

The wind turbines would be about ft tall and have ft diameter rotors. All of the wind energy would be exported to the UK. Element Power estimated the useful service life of the proposed system at 25 years. Element Power stated the proposed system would be entirely independent of the Irish grid. Parasitic power and turbulence interference between wind turbines further degrades CFs. This came up at the World Bank event I wrote about yesterday.

MacKay calculates how much energy could sustainably be produced in the United Kingdom with a massive expansion of existing technology. The total turns out to be less than the nation's energy consumption, which suggests to MacKay that the only path forward is to reduce demand -- through energy efficiency improvements, for example -- until it balances with supply.

Renewable energy advocates typically support conservation efforts, but they don't make reducing consumption their primary goal. Panicked by the urgency of the climate crisis, and rightfully so, their knee-jerk response is a "just do it" approach to technology. To which I say: Why don't we just not do it? Let's not build any new power plants except to replace old, inefficient ones. Let's not dig up all the oil. Let's not drive to work alone. Let's not eat meat every day. Let's not turn the thermostat up so high.

Let's not buy so many things we don't really need. And above all, let's not accept continued energy growth as a necessary or even desirable way of life.

Amid all the news about coal and pollution problems in China you might have missed this one: According to new statistics from the China Electricity Council, China"s wind power production actually increased more than coal power production for the first time ever in Thermal power use, which is predominantly coal, grew by only about 0.

In contrast, wind power production expanded by about 26 TWh. This rapid expansion brings the total amount of wind power production in China to TWh, surpassing China"s 98 TWh of nuclear power. The biggest increase, however, occurred in hydro power, where output grew by TWh, bringing total hydro production to TWh, due favorable conditions for hydro last year and increased hydro capacity. In addition, the growth of power consumption slowed down - in Chinese terms a modest increase of 5.

Besonderer Anlass zur Sorge ist der zu hohe Sockel der Braunkohleverstromung. Letztlich muss der schrittweise Ausstieg aus der Kohle in Angriff genommen werden. Zu Starkwindzeiten oder bei Sonnenwetter wird die Erzeugung aus erneuerbaren Energien sehr hoch, bei anderen Wetterlagen oder zu bestimmten Tages- und Jahreszeiten kann sie niedrig sein. Das gesamte Energiesystem muss sich auf solche qualitativ neuen Anforderungen einstellen, indem es flexibler wird.

Diese erlauben einen weiteren Lastausgleich. Beides sollte in verbindlichen Zielen verankert werden. Insgesamt erachtet der SRU den Vorschlag einer strategischen Reserve als das geeignetere Instrument, da dieser den geringsten Eingriff in den Energiemarkt darstellt. In solchen Situationen stehen die ansonsten aus dem Markt genommenen Kraftwerke bereit. Allerdings werden in dieser Diskussion verschiedene Argumentationsebenen vermengt.

We are massively changing the global environment. Table 1: Policy-relevant potential future tipping elements in the climate system and below the empty line candidates that we considered but failed to make the short list Source " Society may be lulled into a false sense of security by smooth projections of global change. Our synthesis of present knowledge suggests that a variety of tipping elements could reach their critical point within this century under anthropogenic climate change.

The greatest threats are tipping the Arctic sea-ice and the Greenland ice sheet, and at least five other elements could surprise us by exhibiting a nearby tipping point. This knowledge should influence climate policy, but a full assessment of policy relevance would require that, for each potential tipping element, we answer the following questions:.

The IPCC provides a thorough overview of mitigation and adaptation work upon which such a policy assessment of tipping elements could be built. Given the scale of potential impacts from tipping elements, we anticipate that they will shift the balance toward stronger mitigation and demand adaptation concepts beyond incremental approaches , Policy analysis and implementation will be extremely challenging given the nonconvexities in the human-environment system that will be enhanced by tipping elements, as well as the need to handle intergenerational justice and interpersonal equity over long periods and under conditions of uncertainty A rigorous study of potential tipping elements in human socioeconomic systems would also be welcome, especially to address whether and how a rapid societal transition toward sustainability could be triggered, given that some models suggest there exists a tipping point for the transition to a low-carbon-energy system It seems wise to assume that we have not yet identified all potential policy-relevant tipping elements.

Hence, a systematic search for further tipping elements should be undertaken, drawing on both paleodata and multimodel ensemble studies. Given the large uncertainty that remains about tipping elements, there is an urgent need to improve our understanding of the underlying physical mechanisms determining their behavior, so that policy makers are able "to avoid the unmanageable, and to manage the unavoidable" ".

This is the result of a conservative comparison of current feed-in tariffs in Germany with the agreed strike price for new nuclear in the UK Hinkley Point C and current cost estimates for CCS, neglecting future technology cost reductions in any of the four technologies. A meaningful comparison of the costs of different energy technologies should take into account the need for backup capacities and peak load plants.

Such a comparison shows that while additional costs arise for backup gas capacity in a system based on wind and solar PV, these costs are small compared to the higher power generation cost of nuclear. Source: Agora-Energiewende. Wind turbines and transmission lines in Nauen near Berlin, Germany. Observers say the records will keep coming as Germany continues its Energiewende, or energy transformation, which aims to power the country almost entirely on renewable sources by Despite being known for gray skies, the country has installed an astonishing amount of solar photovoltaic PV power — setting multiple solar power generation records along the way.

At the end of , Germany had installed considerably more solar power capacity per capita than any other country. The rapid growth has slowed, however, with 3. And as countries like the U. Regardless, a recent analysis by the consulting firm Eclareon found that solar power has reached grid parity in Germany, meaning once all of the costs are accounted for, the price of commercial solar power is now equal to retail electricity rates.

And wind power reached record output levels last year — producing a massive The unprecedented growth of solar PV in particular has been fueled in large part by policies that incentivize clean energy. Germany's simple feed-in tariff FIT policy, which pays renewable energy producers a set amount for the electricity they produce under long-term contracts, has driven the solar power boom. But as installations continued to outpace government targets, Germany announced last year that it would begin scaling back its feed-in tariff. The FIT is financed by a surcharge paid by utility customers, but a major part of the problem stems from the fact that industry is largely exempt from the renewables surcharge — meaning the burden falls on households.

Along with cutting out fossil fuel-generated energy to a large extent, the transition to renewables includes completely phasing out nuclear power. These goals are only achievable in combination with greatly reduced energy demand. And retail electricity rates are high and rising , putting pressure on lower income individuals in particular. But many of the criticisms are largely overblown, according to Amory Lovins of the Rocky Mountain Institute.

As long-term contracts expire, the past few years' sharply lower wholesale prices could finally reach retail customers and start sending households' total electricity prices back down. Challenges aside, Energiewende — rooted in the acknowledgement that a fossil fuel-based energy system is not sustainable — is remarkable for its scope and its widespread support, particularly in a heavily industrialized country like Germany.

Once all its costs are accounted for, the price of commercial solar power has pulled even with retail electricity rates in Italy and Germany, according to a new report in Cache. The analysis is the third installment in a regular report by the consulting firm Eclareon, done on behalf of an international group of sustainable energy interests. This installment was also the first to look at solar power in the commercial sector rather than the residential sector. The analysis also looked at the level of regulatory support solar enjoys in each country.

The X axis. This does not mean subsidies. As a result, meaningful market competition between solar power and other forms of electricity is really hard to come by, even when their respective prices have pulled alongside one another. None of the countries have an ideal circumstance. But some — those in the top right-hand quadrant — get closer to a world in which electricity is generated not just by a small number of really big suppliers, but by lots and lots of little suppliers as well, and everyone can buy and sell electricity to everyone else as they see fit.

HT: CleanTechnica. Retail Electricity Rates im Cache. The value and structure of the electricity rates in each location will have an impact on the economic decision of self-consuming PV electricity or buying electricity from the utility. The structure of a utility rate can range from a simple flat charge to a complex combination of charges that depend on various factors: Energy costs, which increase with electricity demand kWh. Capacity costs, which vary with peak power demand kW. TOU rates. Availability of rates that increase with the amount of electricity purchased i.

Generally, PV self-consumption will be attractive whenever LCOE is lower than the energy costs charged by the utility for each kWh consumed from the grid. Moreover, if PV self-consumption results in a change on the consumption pattern of the user, the additional avoided costs should also be accounted for within the LCOE calculation. In this regard, capacity costs can decrease as a result of a reduction of peak demand from the grid. However, for this to happen, several conditions must be met.


The following illustration exemplifies this situation: As the above Figure shows, for a commercial consumer it is not easy to save on capacity costs on a given month. This is due to the following reasons: On some months, PV generation is interrupted by the presence of clouds. On other months, peak load reduction is limited by the magnitude of the second highest peak demand, which does not coincide with PV generation. In this analysis, the capacity charge will not be included, but the reader should bear in mind that throughout the lifetime of the PV system it is possible that some savings of capacity charges can be reached, albeit small.

There's a really interesting new study out that compares the carbon footprint of solar panels manufactured in Europe and China. The basic result shows that because Chinese manufacturing is less energy efficient, and reliant on coal fired electricity, the Chinese panels have a bigger carbon footprint. In fact the footprint of Chinese panels is double that of European ones, as you can see in chart from the study to the left.

Brad Mattson, the CEO of Siva Power, said he's learned from the mistakes of companies that tried to scale too quickly or overestimated their ability to reduce costs. After years of experimenting with different materials and production processes, Siva eventually settled on co-evaporated CIGS on large glass substrates. Mattson called the technology "a gift of physics" that offers the highest thin film efficiencies and the fastest production process.

This is the company's newly released cost roadmap, which Mehta notes is "essentially a bunch of numbers in a spreadsheet. The projections factor in labor, energy and water requirements, equipment needs, materials and overhead. Siva says its first megawatt production line will produce CIGS modules at 40 cents per watt. After another two years of operation, the company believes it can get all-in costs down to 28 cents per watt.

The Department of Energy has set a production cost target of 50 cents per watt by In March, Jinko solar reported that it was producing crystalline silicon modules for 48 cents per watt. According to GTM Research's analysis, top Chinese producers could be making solar modules for 36 cents per watt by Mattson told GTM's Eric Wesoff that he believes those numbers are "completely unsustainable" because they don't factor in large subsidies from the Chinese government. So is Siva's plan "sustainable," considering that the company hasn't even built out its first pilot production facility?

Mattson continues to talk about the "gigawatt era" in solar. The most obvious issue is timing. Due to technical problems related to deposition, CIGS thin film producers have historically underestimated their time to scale. The biggest technical challenge for Siva will be ensuring uniform deposition on the large glass substrates while keeping production levels high. Applied Materials also used large glass substrates for amorphous silicon thin film. That ended poorly , mostly due to efficiency issues. For now, Siva's cost structure will sit in a spreadsheet untested until the firm builds out its first production line.

The project is being erected 90 kilometers west of the island of Sylt in water depths between 25 and 37 meters within the exclusive economic zone off the German North Sea coast. A pioneering service plan for the project will generate synergy from its close vicinity to DanTysk offshore wind farm , utilizing joint operations to drive down the maintenance costs of both projects. Vattenfall has contracted Siemens to perform maintenance services on the Sandbank installations for an initial period of five years.

Siemens' Model SWT They combine the proven technology of the most-built offshore wind turbine series - over units worldwide rated at 3. What is more, the unit's rotor - measuring meters in diameter - delivers optimum energy yield even at low and moderate wind speeds.

Hence, once commissioned at the end of , Sandbank will count among the most modern offshore wind farms anywhere in the world. Construction is scheduled to commence in summer The amount of solar photovoltaic capacity MW peak in the United States has tripled in the past 2 years. For comparison: Germany added by J. Other rising stars include New York, Vermont and Georgia, which have large or fast-growing solar energy markets and strong new solar policies or programs implemented since mid Unfortunately, the success of solar power in these and other states has been threatened by recent attacks by fossil fuel interests and electric utilities on key solar policies, such as net metering.

Despite those attacks, many states have reaffirmed and expanded their commitments to solar energy over the past year by increasing solar energy goals and implementing new policies to expand access to clean solar power. Solar energy is on the rise - especially in states that have adopted strong public policies to encourage solar power. Table ES California and Massachusetts both advanced two spots in the rankings to fourth place and eighth place, respectively, significantly increasing their per-capita installed solar energy capacity. America's leading solar states have adopted strong policies to encourage homeowners and businesses to "go solar.

In nearly all of the leading states, consumers are compensated at the full retail rate for the excess electricity they supply to the grid. Beyond the Top 10 states for per-capita solar energy capacity, there are several "advancing" states that have accelerated growth of their solar energy markets by embracing solar-friendly policies. Strong public policies at every level of government can help unlock America's potential for clean solar energy.

To achieve America's full solar potential:. The figures in this report do not include other solar energy technologies, such as solar water heating. V DGRV. Energiegenossenschaften haben bislang rund 1,35 Milliarden Euro in den Ausbau Erneuerbarer Energien investiert. Klimakommune Saerbeck Weitere Informationen. Bisher funktionierte das auch ganz gut. Doch mit den neuen Anlagen geht das nicht mehr.

Das passt gar nicht zum Konzept der kommunalen Energiewende, wie sie Saerbeck verfolgt. Roos: "Unsere Intention war von Anfang an, dass die Genossenscaft etwas produziert und die Genossen selbst daran teilhaben.

Renewables outpace nuclear in economies making up 45 percent of world population. Almost half of all added electricity generating capacity in was from renewables, excluding large hydro-dams, the report said.

In output terms, China, Japan and India, which are three of the world's four largest economies, along with Brazil, Germany, Mexico, the Netherlands and Spain now generate more electricity from non-hydro renewables than nuclear, it said. In Britain, output from renewables, including hydro, surpassed atomic generation "for the first time in decades", while in the United States the share of renewables was 13 percent, up from 8.


Discounting Japan's moribund industry due to its long-term outage, the report said the world's operating units numbered in , up three from a year earlier, and 47 less than a peak. Earth Overshoot Day has moved from early October in to August 13th this year. The costs of this ecological overspending are becoming more evident by the day, in the form of deforestation, drought, fresh-water scarcity, soil erosion, biodiversity loss and the buildup of carbon dioxide in the atmosphere. The latter will significantly amplify the former, if current climate models are correct.

The carbon footprint is inextricably linked to the other components of the Ecological Footprint — cropland, grazing land, forests and productive land built over with buildings and roads. All these demands compete for space. As more is being demanded for food and timber products, fewer productive areas are available to absorb carbon from fossil fuel. This means carbon emissions accumulate in the atmosphere rather than being fully absorbed.

The climate agreement expected at the United Nations Conference of Parties COP 21 this December will focus on maintaining global warming within the 2-degrees-Celsius range over pre-Industrial Revolution levels. This shared goal will require nations to implement policies to completely phase out fossil fuels by , per the recommendations of the Intergovernmental Panel on Climate Change IPCC , directly impacting the Ecological Footprints of nations.

This is not impossible. In fact, Denmark has cut its emissions over the last two decades at this rate: Since the s, it reduced its carbon emissions by 33 percent. Had the world done the same while not changing the rest of the Footprint , Earth Overshoot Day would be on October 3 this year. This is not to say that Denmark has already reached a sustainable Ecological Footprint. Humanity would require the resources of 2. Business As Usual. By contrast, business as usual would mean using the resources equivalent to two planets by , with Earth Overshoot Day moving up on the calendar to the end of June.

This projection assumes that biocapacity, population growth and consumption trends remain on their current trajectories. However, it is not clear whether a sustained level of overuse is possible without significantly damaging long-term biocapacity, with consequent impacts on consumption and population growth. It is not just good for the world, but increasingly becoming an economic necessity for each nation.

We all know that the climate depends on it, but that is not the full story: Sustainability requires that everyone live well, within the means of one planet. More on Earth Overshoot Day: www.
