Electricity: Status of Residential Deployment of Solar and Other Technologies and Potential Benefits and Challenges
GAO-17-142: Published: Feb 13, 2017. Publicly Released: Mar 15, 2017.
Federal and state policymakers have used a range of policies to encourage the deployment of solar systems and other technologies that allow residential customers to generate, store, and manage their electricity consumption. For example, federal tax incentives—such as the investment tax credit—have reduced customers' up-front costs of installing solar systems. In addition, a Department of Energ...
Renewable Fuel Standard: Low Expected Production Volumes Make It Unlikely That Advanced Biofuels Can Meet Increasing Targets
GAO-17-108: Published: Nov 28, 2016. Publicly Released: Nov 28, 2016.
The federal government has supported research and development (R&D) related to advanced biofuels through direct research or grants, and the focus is shifting away from cellulosic ethanol and toward drop-in biofuels. Unlike corn starch-based or cellulosic ethanol, drop-in fuels such as renewable gasoline are fully compatible with existing infrastructure, such as vehicle engines and distribution pip...
DOD Renewable Energy Projects: Improved Guidance Needed for Analyzing and Documenting Costs and Benefits
GAO-16-487: Published: Sep 8, 2016. Publicly Released: Sep 8, 2016.
The Department of Defense (DOD) has emphasized working with private developers using a variety of alternative financing mechanisms—that is, agreements with private developers to pay back the costs of the projects over time—to develop renewable energy projects greater than 1 megawatt. According to DOD officials, DOD works with private developers because doing so gives DOD several advantages. Fo...
