Land use impacts of solar wind and nuclear energy.

Does wind and solar take up too much land to be practical? Does the extreme energy density of nuclear fuel make it the ecologically ideal energy source? In this post, I run the numbers on the land use impact of wind, solar, nuclear and other energy sources.[read more]

Wind and Solar Will Soon Become the 'Least-Cost Option Almost Universally'

Wind and Solar Costs

Two new reports on global demand for renewables forecast dramatic growth in nearly every region of the world over the coming decades. While promotion policies are still important for supporting the industry, conventional technologies like wind and solar are becoming cheap enough to compete without subsidies.[read more]

Procuring Clean Energy in the Developing World: The Appeal of Auctions and the Way Forward

Developing Nations, Clean Energy

Meeting rising energy demand with cost-effective new generation capacity is a critical challenge facing most developing countries. As policymakers and regulators seek out support schemes for clean energy, one procurement mechanism seems to lead the charge – the renewable energy auction.[read more]

Proposed Clean Power Plan Would Accelerate Renewable Additions and Coal Plant Retirements

Effects of the Clean Power Plan

The EPA's Clean Power Plan shows that renewables play a critical role under a range of different market and policy assumptions. The key difference across the various scenarios analyzed involves when and how wind and solar generating capacity additions occur, as well as retirements of coal generation capacity.[read more]

Power Generation and Cost

When power plants are built, several factors influence the choice of fuels and technologies that will ultimately generate electricity. Cost is one of the most difficult factors to compare, as technologies can have vastly different capital, fuel, maintenance, and financing costs, as well as different utilization rates.[read more]

DoE Finds Wind Energy Will Have Largest Role in Cost-Effectively Meeting Clean Power Plan

June 3, 2015 by Michael Goggin

Clean Power Plan Compliance

Low-cost, zero-emission wind energy will become even more valuable as states and utilities develop plans to cost-effectively reduce carbon pollution to comply with EPA’s Clean Power Plan, according to new economic analysis from the Energy Information Administration.[read more]

Will Natural Gas Generation Slow Progress on Climate and Renewables?

June 1, 2015 by Andy Stone

Natural Gas and GHG Emissions

In the US natural gas doesn’t just displace coal, it acts as a substitute to cleaner forms of generation to a very significant degree. This effect isn’t universal, and in China natural gas is expected to substitute largely for coal, with a much smaller impact on wind power.[read more]
