This paper examines how optimal renewable energy (RE) support (RES) policies need to be adjusted to account for carbon prices. We show theoretically and empirically that changing carbon prices requires adjusting RE production subsidies due to two different motives: First, RE premiums need to be...

Subsidies to renewable energy are costly and contentious. We estimate the reduction in prices that follows from the subsidized entry of wind power in the Nordic electricity market. A relatively small-scale entry of renewables leads to a large-scale transfer of surplus from the incumbent...

Power systems with increasing shares of wind and solar power generation have higher capital and lower operational costs than traditional technologies. This increases the importance of the cost of finance for total system cost. We quantify how renewable policy design can influence cost of finance...

There is general agreement that cost-effective environmental regulation uses market mechanisms, such as a tax or a cap-and-trade program, in order to leave choices about the least-cost ways of achieving policy goals to individual producers and consumers. A renewable electricity standard (RES) is...

A variety of renewable electricity policies to promote investment in wind, solar, and other types of renewable generators exist across the United States. The federal renewable energy investment tax credit, the federal renewable energy production tax credit, and state renewable portfolio...

The European Council has proposed to stick to a more ambitious GHG target but to scrap a binding RES target for the post-2020 period. This is in line with many existing assessments which demonstrate that additional RES policies impair the cost-effectiveness of addressing a single CO2...

Since the onset of the COVID-19, the seriousness of the climate problem has attracted more attention, and international cooperation to prevent climate change and climate disaster is continuing. More than 100 countries, including the EU, China, and Japan, have declared or are pursuing carbon...

When considering that increasing CO2 emissions are one of the most important reasons for global warming, the prospect for energy transition emerges as a significant way to combat this issue. Although there is a high correlation between CO2 emissions and fossil fuel consumption, nonrenewable...

Despite ambitious climate goals and already substantial stocks of developed fossil energy reserves, development of new fossil energy reserves continues to be high. This raises concerns, as it reinforces the fossil industry’s opportunities and incentives to continue extraction, and may...

The Republic of Korea fully launched its green finance scheme in 2009 and then introduced the environmental information disclosure system and the emission trading scheme in 2013 and 2015, respectively. However, their use has not increased dramatically, as the public sector has taken the major...
