The Implicit Carbon Price of Renewable Energy Incentives in Germany

Abstract

This research analyzes the German experience in promoting Renewable Energy (RE) as an instrument to reduce GHG emissions. It identifies the cost of reducing CO 2 emissions in the power sector through the promotion of wind and solar energy for the years 2006-2010. A RE carbon surcharge and an implicit carbon price due to the RE incentives are calculated. The RE carbon surcharge is the ratio of the net cost of the RE over the CO 2 emission reductions resulting from actual RE injections into the electric power system. The implicit carbon price is the sum of the RE carbon surcharge and the EUA price. Results show that for the period analyzed both the RE carbon surcharge and the implicit carbon price of wind are on the order of tens of euro per tonne of CO 2 , while for solar are on the order of hundreds of euro per tonne of CO 2 .

In search of politically feasible policy-packages for sustainable passenger transport: insights from choice experiments in China, Germany, and the USA

“…Such policies are hardly implemented as policy-makers tend to adopt policies supported by the population majority (Stehr 2015, Anderson et al 2017. This results in a dilemma between political feasibility and policy effectiveness, where potentially effective policy-interventions run into political feasibility problems and vice versa (Marcantonini and Ellerman 2015, Carattini et al 2017, Gunningham and Sinclair 2017. Nonetheless, we argue that this presumed dilemma is unlikely an 'either-or' problem and, instead, poses a challenge in designing policy-interventions that are as effective as political feasibility considerations allow.…”

Is renewable energy a cost-effective mitigation resource? An application to the Spanish electricity market

“…Compared with the literature, Marcantonini and Ellerman (2015) found an average implicit carbon price (i.e. net cost without carbon cost saving divided by CO2 emission reduction) of 57 EUR/tCO2 for wind power and 552EUR/tCO2 for solar energy in Germany (the huge difference between these two prices is attributed to the fact that the remuneration per MWh in Germany is much higher for solar than for wind, as it happens in Spain).…”

Uncertainty management and the dynamic adjustment of deep decarbonization pathways

“…More targeted subsidies, such as feed-in tariffs (FIT), are needed to induce innovation in more costly energy technologies, such as solar PV in the past (Johnstone, Haščič, & Popp, 2010). But maintaining a high level of incentives for a rapid development of renewables can quickly become unsustainable (Marcantonini & Ellerman, 2014) unless cost-competitiveness is reached fairly rapidly.…”
