These 3 States Have a Head Start on the Clean Power Plan. You’d Never Guess Who They Are.

By EDF Blogs / Published: November 5, 2015

Everyone in Colorado skis, all Oklahomans can rope a calf, and native New Jerseyans like me all talk like Pauly D did onJersey Shore. Right?

You may also stereotype when it comes to clean energy: Progressive states such as California are pumping out clean, renewable energy while others insist on clinging to old, dirty power plants. Well, it’s more complicated than that.

California, which has a market-based system for cutting carbon pollution, does lead the country. But a number of states nationwide, including notably Nevada, Texas and North Carolina, are also making great progress on clean energy – which may surprise some.

Their success is evidence that the supposed divide on clean power may be more about politics than economics and opportunities on the ground.

And that bodes well for the federal Clean Power Plan’s goal of reducing emissions from America’s power plants. Because if Texas is well-positioned to comply, why couldn’t other states do the same? Read More »

5 Energy Trends Driving Climate Progress in 2015

By Ben Ratner / Published: October 29, 2015

What a difference a year can make. Even before the last weeks tick away, 2015 stands out as a remarkable and dynamic year for climate and energy in the United States.

Read on for five bold trends that are beginning to reshape our economy – and our national discourse on climate change.

1. Investments in renewables soar

I admit it: For years, I thought renewable energy was more hype than reality. I’m happy to report that recent data proves me wrong.

In just five years, solar panel prices have fallen 80 percent, and solar capacity installed worldwide grew more than six-fold. The overall cost of solar per kilowatt-hour, meanwhile, plummeted 50 percent.

For the first time in history, energy from the sun is as cheap as traditional energy in states such as Arizona, California and Texas.

The proof is in the pudding. Apple, for example, recently signed an $848-million power agreement with a solar provider – bypassing the electric grid. A deal of this magnitude shows where solar is today, and where it is headed. Read More »

The Future of Energy Storage is BYOB

By EDF Blogs / Published: October 13, 2015

By: Michelle Zheng, Clean Energy Intern

Before the U.S. electric grid became centralized under utilities and independent system operators, it consisted of unorganized and unconnected generators. As distributed energy resources (DERs) – such as rooftop solar, energy storage, and other generation sources beyond large power plants – find their way into (and onto) more homes and businesses, it’s clear the grid’s future has a lot in common with its roots. This time, however, an array of new technologies will help us take advantage of a more decentralized approach.

But are utilities ready to handle this change? Although some are eager to try, the answer under most current utility business models is a resounding “no.” This is because current business models promise utilities profit for putting more steel into the ground and selling as much energy as possible – the exact things DERs help avoid.

Despite all this, can we find ways for utilities and DERs to be friends? We think so. Meet the “Bring Your Own Battery” (BYOB) model. Developed by San Diego Gas & Electric (SDG&E) and collaborators at Rocky Mountain Institute’s eLab Accelerator, it capitalizes on the emerging movement of customers bringing their own batteries to the grid. What’s more, it creates a role for the utility to facilitate rather than fight the expansion of DERs.

Three Technologies that will Keep Energy Costs in Check

By Jim Marston / Published: September 2, 2015

Many American households and businesses saw energy costs soar this summer with July being the hottest month in Earth’s hottest year on record.

Utilities rely on “peaker plants” during these record-setting heat waves to avoid blackouts. Such plants are more expensive and often more polluting to operate, and utilities pass the higher costs straight on to their customers.

Fortunately, this energy equation is changing. Innovative pricing and smart energy systems are gradually taking hold across the United States, already allowing homes and businesses to save energy and cut costs. It’s just the beginning of what I call our next energy revolution.

Here are three technologies on the market today that are fueling this trend: Read More »

Orange is the New Black, 40 is the New 30…and Energy Storage Could be the New California Power Plant

By Larissa Koehler / Published: June 26, 2015

If you follow pop culture, you’ve likely heard that Orange is the New Black, and 40 is the new 30. A perhaps lesser known – but equally important – new comparison that is turning heads in California is that energy storage might just be the new power plant.

This probably warrants a bit of explanation. On a power grid without storage, solar energy is generated during the day when the sun is shining its brightest, providing clean, renewable energy to homes and businesses – thus lessening the hold on the grid of dirty power plants. But what happens when this energy source goes offline? As people come home after work and turn on TVs, run dishwashers, and fire up other hungry appliances (also referred to as “peak” energy hours), the grid must rely on fossil fuel-powered electricity to ramp up production quickly.

However, when energy storage is added into this mix, a shift occurs. If there is enough renewable energy stockpiled during the sun’s most productive hours, between 11 AM and 3 PM, then the use of fossil fuels at peak times can be reduced. In this way, new fossil fuel power plants that might be necessary to meet increased population and demand can be avoided. And voila: energy storage is the new power plant. Read More »

5 Reasons Clean Energy Investments Beat Expectations

By EDF Blogs / Published: May 20, 2015

By: Karin Rives, editor of EDF Voices

The solar industry is booming and the U.S. Department of Energy’s loan guarantee program, chastised after several high-profile cleantech companies went belly up in 2011, has more than recovered.

In fact, leading venture capitalists, some of our largest banks and brands, and – lately – private investors are expected to continue to invest heavily in clean energy projects this year after the market rebounded with a vengeance in 2014.

Here are five reasons why. Read More »
