Summer, Solar, and an Iceberg of Excuses: Why I Don’t Have Rooftop Solar (and Why I’m Wrong)

I’ve got a confession to make: For all the talking I do about solar and the solar revolution underway, I haven’t thrown my hat in the solar ring. An iceberg-sized collection of excuses stands between me and Solardom, and my homeowner-ship is hesitant to steam past them. But here’s why my excuses might just be hogwash, and how that iceberg might just melt away under the summer sun. Read More

New Flawed Study of the Clean Power Plan: How the MISI Study Gets It So Wrong

An op-ed in yesterday’s Investor’s Business Daily uses a new study to make unsubstantiated claims about the economic impacts of the proposed Clean Power Plan on vulnerable communities. Since the op-ed didn’t provide a link to the actual analysis, we hunted it down and took a look behind the headlines. And when we did, we found that the foundations of this new “analysis” are shaky indeed. Read More

The EPA’s Clean Power Plan: Setting the Record Straight on the Benefits and Costs

We’re working hard to set the record straight on disinformation about the Clean Power Plan, the first-ever national limits on carbon pollution from existing power plants under the Clean Air Act. It’s not hard to find fodder: there’s plenty of misleading stuff out there, and some of it has gotten way more airtime than it should have. To fight back, colleagues and I gave a webinar recently on the really wrong conclusions some studies have come to on the Clean Power Plan, and how they got it so far off the mark.

Annual Energy Outlook 2015: EIA Consistently Lowballs Renewables, Undercuts Climate Change Efforts

The U.S. Department of Energy’s Energy Information Administration is about to publish its annual best guess as to what the future will hold, energy-wise. But if the past is any guide, their best guess is likely to lowball renewable energy’s potential contribution. That has real implications for our nation’s efforts to tackle climate change. Here’s what to watch for when the 2015 Annual Energy Outlook comes out, and why it matters. Read More

Portland Sunnier Than Houston? Solar Power Resources Are More Widespread Than You Think…

The spring equinox is a fine time to celebrate the sun. And, for the solar power lovers among us, it’s a great time to take stock of how much sun is available for rooftop solar across the country.

When we do, we find that, over the course of the year, the sun for solar power generation is actually much more evenly distributed than sunny-Southwest-postcards-vs.-Northern-snow-scenes would suggest. It’s also more evenly spread than typical solar maps would lead you to believe. Here’s a better way to see how much you’ve got. Read More

Where Florida’s Electricity Comes From, and How It Can Do Better

Florida has been on my mind lately, as storm after storm has piled the snow up outside my door and relatives have called from the Sunshine State to report on the (rather higher) temperatures they’re experiencing. But the state has also been attracting attention with its electric sector moves—some positive, some less so.

When it comes to electricity, the Sunshine State is still far short of living up to its clean energy potential. Here’s how and why decision makers should fix that. Read More
