How Many Homes Have Rooftop Solar? The Number is Growing…

Remember when the most likely place to glimpse solar in action was the little strip attached to a pocket calculator? Well, fortunately solar photovoltaic (PV) technologies have come a long way, and now it’s common to see PV panels on residential and commercial rooftops around the country. This dramatic rise in residential solar PV installations is depicted below in UCS’s new solar infographic. From 2006 to 2013, the number of homes with solar grew by more than 1,000 percent.

There Oughtta Be a Law to Fix the Grid—and There Is!

Federal policies to introduce more choice in electricity supplies, and competition from new technologies and companies, continue to evolve and improve. These reforms have greatly fostered the growth of renewable energy across the United States. And a court decision today will help ensure that they continue to do so.

The Economist Ignores Reality, Highlights Flawed Renewable Energy Study

A recent article in The Economist covers a study comparing the costs of solar, wind, hydro, nuclear, and natural gas. Alas, the study starts with a fundamental misunderstanding of how our electricity system works, and goes  downhill from there. And The Economist’s attention unfortunately helps to perpetuate those errors. Here are five examples of what went wrong. Read More

Fracking: Energy Abundance or Crisis?

As the boom in fracking wells in the northern Appalachian Marcellus shale region now produces seven times more natural gas (methane) than in 2010, the implications for policy and impacts on the energy market are starting to show. Read More

Hot Models Try to Forecast CO2 Reductions

A hot chase over models began soon after the Environmental Protection Agency (EPA) released draft CO2 rules June 2. Reducing CO2 (carbon-dioxide, the climate-altering pollution) in the electricity sector is not a mystery, but expecting too much from a model can be frustrating. With the CO2 rules, we have entered a new era, triggering a great clamoring amongst policymakers and advocates to get comfortable with the models. Temperatures are rising, and it is not just the hot summer weather. Read More

Even as Coal Use Declines, Most States Are Still Dependent on Coal Imports

The use of coal to produce electricity in the United States has been declining in recent years. Yet for most states still heavily dependent on coal-fired power, the cost of importing coal continues to be a drain on local economies. According to a new Union of Concerned Scientists (UCS) analysis, 37 states were net importers of coal in 2012, paying a total of $19.4 billion to import 433 million tons of coal from other states and even some foreign countries. Instead of sending billions of ratepayer dollars out of those states year after year, consumers would be better served by investing more in local renewable energy development and energy efficiency measures.

Climate Science, Nuclear Power, and a Renewable Energy Future

Contrary to the public assertions made this week by some of our climate scientist friends, nuclear power is likely to have a limited near-term role in avoiding the worst impacts of climate change. Renewable energy technologies are cheaper, less risky, and ready for deployment today. A look at where things stand with both nuclear and renewables bears all that out. Read More
