Imagine homeowners and businesses saving millions of dollars – and cutting pollution – without needing to do anything. Magic? No, but it does require electric utilities to take advantage of new technologies that better provide customers with just the right amount of voltage to their electrical outlets.
Many appliances, including incandescent lighting, work just as effectively, yet consume less energy, when the flow of electricity to them is reduced. Put another way, higher voltages generally make individuals and businesses needlessly use more energy, driving up electricity bills and air pollution. Therefore, if voltage was “right-sized,” residents would get enough power to run their appliances efficiently, but not so much that they use more electricity than needed.
What we’ve described above is “voltage optimization,” and a new study by Commonwealth Edison Company (ComEd) looking at this technology’s potential within Chicago and northern Illinois found it could reduce the need for almost 2,000 gigawatt-hours of electricity (enough to power 180,000 homes) each year at an amazingly low cost of less than two cents per kilowatt-hour – more than is achieved now from the utility’s other efficiency programs. This translates to $240 million per year in savings for ComEd’s customers, of which 90 percent could potentially benefit. The study also suggested full deployment of voltage optimization would only take about five years. Read More
Last June, the Environmental Protection Agency (EPA) proposed the first ever national carbon pollution standards for existing power plants. Fossil fuel-fired power plants account for almost 40% of U.S. carbon dioxide emissions, making them the largest source of greenhouse gas emissions in the nation and one of the single largest categories of greenhouse gas sources in the world.
Under the Clean Power Plan, these emissions will decline to 30% below 2005 levels by 2030 – accompanied by a significant decline in other harmful pollutants from the power sector, such as sulfur dioxide and oxides of nitrogen. The power sector is already halfway to this target, already 15% below 2005 levels.
The EPA has carefully designed the Clean Power Plan to provide extensive flexibility so that states and power companies can continue to deliver a steady flow of electricity while deploying cost-effective measures to reduce carbon pollution over the next fifteen years. Read More
Last month, I attended the Vail Global Energy Forum in Colorado. Billed as a “mini-Davos” of energy (studiously ignoring the Aspen crowd a few hours down the highway), that moniker may have felt aspirational when the conference launched three years ago. But, this year it paid off: momentum for frank dialogue and global innovation is building on the slopes of the Vail Valley.
Here’s my take on how the clean air of the mountains cuts through the hot air of energy debates to illuminate practical, actionable ideas.
Three big ideas drove the conference:
- North American energy independence
Mexico, the United States, and Canada could, together, innovate their way to an energy marketplace that weakens dependence on overseas imports, scales up clean energy solutions, and charts a path to low-carbon prosperity. At times, the discussion was framed by the rise of unconventional oil and gas exploration (yes, “fracking”), collaboration around pipelines (yes, “Keystone”), and whether these could disrupt traditional geopolitical frames.

When the door to one power plant closes, a window to more clean energy solutions opens.
It may seem logical that once a power plant closes, another one needs to be built to replace it – after all, we need to make up for its potential energy generation with more natural gas or nuclear-powered energy, right? San Diego Gas & Electric (SDG&E) is certainly trying to convince Californians this is true. Trouble is, EDF and other environmental groups, along with the California Public Utilities Commission (CPUC), aren’t buying it. And you shouldn’t either.
This story begins in 2013, when the San Onofre Nuclear Generating Stations (SONGS) permanently closed, shutting down a nuclear power plant with a capacity of 2,200 megawatts (MW) and sparking a debate about how to replace this lost power source. When first determining how to proceed in the wake of the SONGS closure, the CPUC decided SDG&E could buy between 500 to 800 megawatts (MW) of new energy resources by 2022. Further, at least 200 MW of this power had to – and all of it could – be met with preferred resources like energy efficiency, renewable energy, energy storage, and demand response (an energy conservation tool that pays people to save energy when the electric grid is stressed).

By: Charlene Heydinger, Executive Director, Keeping PACE in Texas
Today marked a milestone for Texas’ clean energy economy. Travis County voted to adopt the Property Assessed Clean Energy (PACE) program, making it the first county in Texas to do so. This means Austin and the surrounding area will soon reap the economic and environmental benefits from giving energy-intensive, thirsty Texas a reprieve with water efficiency and clean energy.
What is PACE?
PACE, enacted during the 2013 Texas Legislature with support from both sides of the aisle, has the potential to unlock a considerable amount of private funding for clean energy projects in the state. Specifically, it is an innovative financing program – completely free of government mandates and public funding – that enables commercial, industrial, multi-family, and agricultural property owners to obtain low-cost, long-term loans for water conservation, energy-efficiency, and renewable energy projects. Participants will then repay these loans for clean energy projects through their property tax bill. Read More

The U.S. Environmental Protection Agency (EPA) is hard at work right now on the Clean Power Plan – the first ever national carbon pollution standards for power plants.
Among the many important aspects of this historic plan, we believe this: It is critical that EPA finalize carbon pollution standards for the power sector that include protective, well-designed standards beginning in 2020.
Power plants account for almost 40 percent of U.S. carbon dioxide emissions, making them the largest source of greenhouse gas emissions in the nation and one of the largest sources of greenhouse gases in the world.
The Clean Power Plan will be finalized this summer. When fully implemented, it is expected to reduce greenhouse gas emissions from the power sector to 30 percent below 2005 levels. That makes these eminently achievable and cost-effective standards integral to climate security, human health, and prosperity. Read More
