The U.S. Environmental Protection Agency’s (EPA) new Clean Power Plan will empower states to design customized, cost-effective programs to reduce climate-destabilizing pollution while ensuring continued electric system reliability.

States will be able to deploy flexible compliance mechanisms such as:

  • renewable energy
  • demand-side energy efficiency
  • shifts in utilization away from higher-emitting and towards lower-emitting generation sources
  • measures at specific plants to secure reductions in carbon pollution

And states will be able to do all of this while designing their compliance plans to make sure that generation resources are fully sufficient to ensure reliability. Read More »

Power Plant Rule a Tipping Point for Clean Energy Economy

powerplantruleFor those of us (and all of you) who’ve been urging the government to implement meaningful climate policy, the release yesterday of a plan to cut carbon emissions from power plants has been a long time coming. But it finally came.

The U.S. Environmental Protection Agency’s proposed carbon pollution rule for existing fossil-fueled power plants – also known as the Clean Power Plan – are a huge win for our climate.

We also think it could go down in history as the tipping point in our nation’s transition to a clean energy economy. Here’s why:

Old, dirty power plants will be retired

The nation’s fleet of coal-fired power plants is the single largest source of carbon pollution in the U.S. and one of the largest in the world. Placing carbon regulations on this source of electricity for the first time in history will transform our energy system. Read More »

U.S. Climate Assessment Report Warns of Energy Challenges – All of which We’re Ready to Meet

There’s been plenty of attention paid to the recent release of the Third National Climate Assessment report – and appropriately so. The lead paragraph of New York Times reporter Justin Gillis’ story put it rather bluntly:

“The effects of human-induced climate change are being felt in every corner of the United States, scientists reported Tuesday, with water growing scarcer in dry regions, torrential rains increasing in wet regions, heat waves becoming more common and more severe, wildfires growing worse, and forests dying under assault from heat-loving insects.”

Even for those of us that have been urging U.S. action on climate, the assessment was pretty stark and the message was clear: the time to act came a long time ago. We need to get busy catching up.

But the optimist in me was excited about a chapter in the report that hasn’t yet gotten much attention. Chapter 4 focuses on Energy Supply and Use, and though the energy challenges caused by climate change are formidable, the U.S. is very well positioned to meet them if our leaders will get behind some practical solutions. There are five key takeaways in the Energy chapter: Read More »

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future

Clean energy resources, like wind, solar, and energy efficiency, have certain key advantages over traditional, fossil fuel-based resources: they don’t require expensive, polluting fuels or large capital investment, consume little to no water, generate negligible carbon emissions, and are easily scalable. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant. That’s where demand response, a people-driven solution, comes in.

On a hot summer day, for example, electricity use rapidly increases as people turn on air conditioners to avoid the heat of the late afternoon. A decade ago, the grid operator’s only option is to turn on another fossil fuel power plant to meet the increased need for electricity. But, at any given time, there are thousands of light switches left on, idle water heaters, cycling swimming pool pumps, and forgotten thermostats that people could temporarily turn off or down, if only they were offered the right incentive. If asked, people can adjust their power usage in exchange for a financial reward. We call this “demand response,” and it is increasingly helping to balance the flow of electricity with our energy needs at a given moment.

Demand response diverts money that would generally go to a fossil fuel power plant to homeowners and businesses instead. In this scenario, a utility or demand response provider sends a message for participants to reduce electricity use at key times in exchange for a credit or rebate on their utility bill, in addition to the cost savings they will earn through conservation. Of course, participants always have the option to opt-out with the tap of a button on their smart phone or thermostat. Read More »

An In-Depth Look at the Future of American Energy and How We Get There

Imagine a world where homes not only run on clean electricity but also generate, store, and sell it. A world where power companies get paid for conserving energy, not just producing it. Where, when supplies are tight, the power grid gives customers the option of being paid to reduce and even shift their energy use to a different time of day, allowing us to use more renewable energy.

The U.S. is poised to spend around $2 trillion over the next two decades replacing our outdated electric infrastructure. We must make sure those investments are not spent on replacing old, dirty power plants with more of the same. If we’re truly going to unleash the clean energy future, we must invest in renewable energy and a smarter grid that can smooth out the demand for power and reduce harmful air pollution. Read More »

Changes to Electricity Systems Will Enhance U.S. Grid Reliability

Cheryl Roberto PhotoLast Thursday morning, with my heart quickly jumping, I entered the grandeur of the United States Senate hearing room for the Committee on Energy and Natural Resources’ Keeping the lights on — are we doing enough to ensure the reliability and security of the US electric grid? hearing as an invited witness. I was eager to share EDF’s vision of a cost-effective, clean energy system that enhances reliability − but I couldn’t help being a little awed by the moment. I had never testified on Capitol Hill before and the dignity of the setting and importance of the message I wanted to share weighed on me.

Here are the high points of my testimony (though you can read it in full here):

  • The nation’s electricity system stands at a transformative crossroads: The costs of distributed generation technologies like rooftop solar and battery storage are falling and energy productivity is rising. In our digital world, people have increased demands for power quality and reliability, but needs for power quantity are predicted to fall – mostly due to “gains in appliance efficiency and an increase in vehicle efficiency standards by 2025.” As a result, our system is transforming from a one-way, centralized power delivery network in which customers passively receive electricity to a two-way flow of both power and information in which customers both receive and produce electricity. The very model of centralized, utility-scale power generation is no longer sacrosanct. The electricity systems we built in the last century, and the regulations that govern them, are no longer adequate – neither to ensure reliability, or to accommodate the rapid changes in technology, consumer needs, environmental standards, and the changing marketplace.
