Fossil fuels as coal and oil are currently the biggest CO2 emitters since our power generations are based on them. A way to reduce CO2 emissions is to reduce fossil fuel consumptions and an efficient way to do so is to switch to renewable energies as solar, wind, and hydropower. I am working on ways to do this, how to move away from fossil fuels and start using reliable and clean energy sources as renewable energies.
Abstract: Climate Change Economics, Ahead of Print. Renewable electricity subsidies have been popular policy instruments to combat climate change because of their ability to offset emissions. This paper studies the long-run welfare benefits of optimizing the design of the existing renewable energy subsidy (the status quo) in the presence of heterogeneity in the offset emissions. In particular, I measure the welfare gain from differentiating renewable subsidies across location and time to reflect the environmental benefits from emissions offset in the context of wind energy in the Texas electricity market. I find that the welfare gain from differentiation is small compared to the gain already achieved under the status quo subsidy. In contrast, the optimal emissions tax yields much larger welfare gain because it engages in other cost-effective emissions abatement channels that renewable energy subsidies do not: namely, demand conservation and cross-plant fuel substitution.

Abstract: The key advantage of renewables is that they are free of direct pollution and carbon emissions. Given concern over global warming caused by carbon emissions, there are substantial policy efforts to increase renewable penetrations. The purpose of this paper is to outline and evaluate the challenges presented by increasing penetrations of renewable electricity generation. These generation sources primarily include solar and wind which are growing rapidly and are new enough to the grid that the impact of high penetrations is not fully understood. The intrinsic nature of solar and wind power is very likely to present greater system challenges than “conventional” sources. Within limits, those challenges can be overcome, but at a cost. Later sections of the paper will draw on a variety of sources to identify a range of such costs, at least as they are foreseen by researchers helping prepare ambitious plans for grids to obtain high shares (30–50%) of their megawatt hours from primarily solar and wind generation. Energy poverty issues are outlined and related to renewable costs issues.

Abstract: Small Island Developing States (SIDS) have established ambitious renewable energy targets. The promotion of renewable energy has been motivated by several factors: a desire to lessen dependence on fossil fuels, to attract development assistance in the energy sector, and to strengthen the position of SIDS in climate change negotiations. Here we explore the interplay between the role of aid and energy policy in the development of renewable energy resources in SIDS. We find that the importance of development assistance has implications for the sustainability of renewable energy development, given that funding is not always accompanied by necessary energy policy reforms. We also identify energy efficiency and access to modern energy services as having received insufficient attention in the establishment and structure of renewable energy targets in SIDS, and argue that this is problematic due to the strong economic case for such investments.
