China, the United States, and the European Union take on transmission upgrades

This report examines electricity transmission developments and challenges for renewable energy in the European Union (EU), China, and the United States.

The Two Degrees of Innovation project works with researchers, engineers, policymakers and other practitioners to create the conditions for global innovation in clean energy, from research to deployment.

WRI is accepting participants for Solar@Work, a new solar collaborative purchasing program.

Electricity consumers interested in switching to solar often find that traditional utility metering arrangements based on a “one customer, one meter” model present barriers to selling power back to the grid, siting projects, or owning systems jointly. These limitations are starting to be addressed by more flexible net metering policies in many states.

The Federal Production Tax Credit (PTC) and Investment Tax Credit (ITC) are incentives for development and deployment of renewable energy technologies. This document provides an update on their benefits, applicability to specific technologies, and expiration dates.

Collaborative solar purchasing brings buyers together to reduce the costs of solar energy.

WRI’s new report, in collaboration with CDF-IFMR, looks at the market potential for clean and renewable energy in rural India.

Could a major industrialized country be powered entirely by renewable energy? Germany wants to be the first to try.

This paper analyzes the global integration of the solar photovoltaic (PV) sector and looks in detail at the industry’s recent growth patterns, industry cost structure, trade and investment patterns, government support policies and employment generation potential.

This working paper provides a snapshot of the current investment environment for solar photovoltaic (PV) in the United States and describes the current installation trends, policy landscape, and economics.

Solar photovoltaic systems generate electricity using technologies that capture the energy in sunlight.

In the Southwest United States, an enormous solar energy resource remains largely untapped. There is already more than 500 MW of concentrating solar thermal power in the United States and Spain primarily, but there is significant scope to scale up development. As Congress oversees the nation’s transition to a clean energy economy, a homegrown renewable energy technology—concentrating solar thermal power—can help cut emissions and enhance energy security with American resources.

Australia and other nations rich in solar resources should invest in concentrating solar thermal (CST), a key low-carbon technology.
