ACCCE, NERA, and Another Misleading Study about the Clean Power Plan

, senior energy analyst, Clean Energy

The American Coalition for Clean Coal Electricity (ACCCE) has funded yet another flawed analysis by NERA Economic Consulting to try to shore up the faltering campaign against the Environmental Protection Agency’s Clean Power Plan. This new study is no improvement on the previous one, and actually goes backward in terms of how straight-forward they are about the study’s inputs and assumptions. Read more >

Why The Investigation Of ExxonMobil Matters

, president

Sometimes simple truths lie dormant for a long time until they are powerfully brought to our attention. But, once our understanding is kindled, the implications—and changes in public attitudes—can spread like wildfire, gathering momentum at a breathtaking pace.

That is what seems be to happening right now with a simple, but powerful idea: that, for decades, the world’s largest fossil fuel companies knew all about the harm their products posed to the planet, yet many chose to deceive the public about climate science and block meaningful reform.

What is the Rebound Effect? — Energy Efficiency, Part 2

, Kendall Science Fellow

In my previous post, I noted that energy efficiency by itself does not necessarily reduce emissions, but it does give us the resources to clean up our energy supply. One complicating factor in projecting energy savings from efficiency is the “rebound effect.” Here’s what it is, how it works, and what it means for efficiency. Read more >

Oil Industry Money Buying Too Much Influence in California

, director, California & Western States

It’s been clear to a lot of people for a long time that there’s too much money in politics, and in California the statistics clearly indicate there is too much oil money in politics. Lobbying expenses by oil companies in California reached an astonishing $11 million from July through September of 2015. The third-quarter lobbying expenses paid for an expensive campaign this past summer by Big Oil to derail an oil-reduction provision in California’s ambitious climate legislation, SB 350 (De León and Leno). If that’s not startling enough, the oil industry has spent an eye-popping total of $17.7 million so far this year to influence California energy policies with three months still to go. That annual amount (which is bound to go up even more by year’s end) averages to $147,500 per legislator—a lot more than California’s 120 state senators and assembly members make in their annual salaries.
