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.

The Cost of Installing Solar Panels: Plunging Prices, and What They Mean For You

Installing rooftop solar panels has never been more affordable. UCS’s new solar infographic highlights the remarkable drop in the cost of rooftop solar in recent years, and how people are getting systems for even less, or even for zero dollars down. Here’s how the numbers add up (or down), and why—and how you can get in on the action.

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

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

As EPA Hearings Begin, Colorado Makes Strides toward Reducing Carbon Emissions

On July 30, I will be testifying in support of the EPA’s power plant carbon standard at a hearing in Denver. As one of four locations where the EPA will be seeking public comment on the draft rule this week, Colorado is a mighty fine choice. The Rocky Mountain State is well positioned to exceed its proposed carbon emissions reduction target and serves as an excellent example of how a state can successfully transition toward a low-carbon, clean energy economy.
