This preference came primarily in the form of a subsidy policy based on feed-in tariffs, established in 1991 by the Electricity Feed-in Law, requiring utilities to accept and remunerate the feed-in of “green” electricity at 90 percent of the retail rate of electricity, considerably exceeding the cost of conventional electricity generation.
A subsequent law passed in 2000 guaranteed continued support for 20 years. This requires utilities to accept the delivery of power from independent producers of renewable electricity into their own grid, paying technology-specific feed-in tariffs far above their production cost of ¢2.9-10.2 per kilowatt hour (kWh).
With a feed-in tariff of ¢59 per kWh in 2009, solar electricity generated from photovoltaics (PV) is guaranteed by far the largest financial support among all renewable energy technologies.
Currently, the feed-in tariff for PV is more than eight times higher than the wholesale electricity price at the power exchange and more than four times the feed-in tariff paid for electricity produced by on-shore wind turbines.
Even on-shore wind, widely regarded as a mature technology, requires feed-in tariffs that exceed the per-kWh cost of conventional electricity by up to 300% to remain competitive.
By 2008 this had led to Germany having the second-largest installed wind capacity in the world, behind the United States, and largest installed PV capacity in the world, ahead of Spain. This explains the claims that GermanyÂ’s feed-in tariff is a great success.
Installed capacity is not the same as production or contribution, however, and by 2008 the estimated share of wind power in GermanyÂ’s electricity production was 6.3%, followed by biomass-based electricity generation (3.6%) and water power (3.1%). The amount of electricity produced through solar photovoltaics was a negligible 0.6% despite being the most subsidized renewable energy, with a net cost of about $12.4 billion for 2008.
The total net cost of subsidizing electricity production by PV modules is estimated to reach $73.2 billion for those modules installed between 2000 and 2010. While the promotion rules for wind power are more subtle than those for PV, we estimate that the wind power subsidies may total US $28.1 billion for wind converters installed between 2000 and 2010.
Consumers ultimately bear the cost of renewable energy promotion. In 2008, the price mark-up due to the subsidization of green electricity was about ¢2.2, meaning the subsidy accounts for about 7.5% of average household electricity prices.
Given the net cost of ¢41.82/kWh for PV modules installed in 2008, and assuming that PV displaces conventional electricity generated from a mixture of gas and hard coal, abatement costs are as high as $1,050 per ton.
Using the same assumptions and a net cost for wind of ¢3.10/kWh, the abatement cost is approximately $80. While cheaper than PV, this cost is still nearly double the ceiling of the cost of a per-ton permit under Europe’s cap-and-trade scheme. Renewable energies are thus among the most expensive GHG reduction measures.
There are much cheaper ways to reduce carbon dioxide emissions than subsidizing renewable energies. CO2 abatement costs of PV are estimated to be as high as $1,050 per ton, while those of wind power are estimated at $80 per ton. By contrast, the current price of emissions certificates on the European emissions trading scheme is only 13.4 (Euro) per ton. Hence, the cost from emission reductions as determined by the market is about 53 times cheaper than employing PV and 4 times cheaper than using wind power.
Moreover, the prevailing coexistence of the EEG and emissions trading under the European Trading Scheme (ETS) means that the increased use of renewable energy technologies generally attains no additional emission reductions beyond those achieved by ETS alone. In fact, since the establishment of the ETS in 2005, the EEGÂ’s net climate effect has been equal to zero.
While employment projections in the renewable sector convey seemingly impressive prospects for gross job growth, they typically obscure the broader implications for economic welfare by omitting any accounting of offsetting impacts. These impacts include, but are not limited to, job losses from crowding out of cheaper forms of conventional energy generation, indirect impacts on upstream industries, additional job losses from the drain on economic activity precipitated by higher electricity prices, private consumersÂ’ overall loss of purchasing power due to higher electricity prices, and diverting funds from other, possibly more beneficial investment.
Proponents of renewable energies often regard the requirement for more workers to produce a given amount of energy as a benefit, failing to recognize that this lowers the output potential of the economy and is hence counterproductive to net job creation. Significant research shows that initial employment benefits from renewable policies soon turn negative as additional costs are incurred. Trade-and other assumptions in those studies claiming positive employment turn out to be unsupportable.
In the end, GermanyÂ’s PV promotion has become a subsidization regime that, on a per-worker basis, has reached a level that far exceeds average wages, with per-worker subsidies as high as $240,000.
It is most likely that whatever jobs are created by renewable energy promotion would vanish as soon as government support is terminated, leaving only GermanyÂ’s export sector to benefit from the possible continuation of renewables support in other countries such as the United States.
Due to their backup energy requirements, it turns out that any increased energy security possibly afforded by installing large PV and wind capacity is undermined by reliance on fuel sources — principally gas — that must be imported to meet domestic demand. That much of this gas is imported from unreliable suppliers calls energy security claims further into question.
Claims about technological innovation benefits of GermanyÂ’s first-actor status are unsupportable. In fact, the regime appears to be counterproductive in that respect, stifling innovation by encouraging producers to lock into existing technologies.
In conclusion, government policy has failed to harness the market incentives needed to ensure a viable and cost-effective introduction of renewable energies into GermanyÂ’s energy portfolio. To the contrary, GermanyÂ’s principal mechanism of supporting renewable technologies through feed-in tariffs imposes high costs without any of the alleged positive impacts on emissions reductions, employment, energy security, or technological innovation. Policymakers should thus scrutinize GermanyÂ’s experience, including in the U.S., where there are currently nearly 400 federal and state programs in place that provide financial incentives for renewable energy.
Although Germany’s promotion of renewable energies is commonly portrayed in the media as setting a “shining example in providing a harvest for the world” (The Guardian, 2007), we would instead regard the country’s experience as a cautionary tale of massively expensive environmental and energy policy that is devoid of economic and environmental benefits.
