A Stealth Tool to Modernize the Electric Grid

Electricity regulators, clean energy innovators, and rappers have all lamented poor communication. And some have pushed for cleaner, cheaper, more reliable solutions for meeting our energy needs. This is particularly so with the much anticipated emergence of a new kind of non-event based, price-responsive demand response (DR), or flexible DR.

Whereas traditional DR signals customers to voluntarily and temporarily reduce their energy use at times when the electric grid is stressed, this type of DR does that and more. The big difference? It signals customers, their appliances, and their electric vehicles to increase their energy use when electricity is clean, plentiful, and cheap.

For example, electric vehicles can be programmed to charge at mid-day when the sun is bright and solar energy is at its peak, and use that stored energy when the sun sets. Better yet, many of our cars, homes, and appliances can be programmed to monitor grid conditions in real time, via the Internet, and respond accordingly by charging or defecting. Also known as a “set-it-and-forget-it” feature, this function enables the seamless integration of flexible DR while also supporting the full potential of energy efficiency measures and distributed energy resources (DERs), like rooftop solar and energy storage.

The seamless and stealth nature of this type of DR, which can be largely automated by tools and service providers, is something neither the customer nor the utility have to think about. It’s like a secret agent, operating behind walls and wires to find the greatest energy (and cost) saving-potential. Regulators need to unleash this “secret agent DR” by rewarding it fairly and efficiently in the energy marketplace, giving it a “license to thrill” in households and businesses across California.

California Makes Clean Energy History with Passage of SB 350

By: Lauren Navarro and Tim O’Connorsolar

Every day thousands of Americans suffer from dirty air – costing the young and old their health, livelihood, and in many cases, their lives. As California is home to the top five most polluted cities in the country, we need action.

Thankfully, after many long hours of debate and negotiations at the state capitol, the California Legislature passed SB 350 (De León) last Friday. The California State Assembly passed the bill, with a 52-26 vote with bipartisan support before passing it on to the senate where it was approved in a concurrence vote. This bill increases California’s renewable energy mix to 50 percent and doubles the energy efficiency of existing buildings. Both of these provisions will serve to combat dirty air and fight climate change, while ushering in a new era for the state’s electricity system – one defined by a cleaner, more resilient, and dynamic electric grid.

4 Undeniable Signs We're Making Progress on Climate Change

Stretch as far as eye can see the grass and the horizon distance, wind turbine.

Seven months ago, I made a strong statement that may have left some people shaking their heads. I said that we can turn the corner on climate change – end the centuries-long rise in greenhouse gas emissions and see them peak and begin to decline – in just five short years.

As it turns out, 2015 is shaping up to be a year of giant steps toward that goal.

In a deeply reported New York Magazine piece, political writer Jonathan Chait calls it “the year humans finally got serious about saving themselves.” Says Chait, “The world is suddenly responding to the climate emergency with – by the standards of its previous behavior – astonishing speed.”

I agree. Here are four reasons I believe we’re headed in the right direction: Read More »

Three Technologies that will Keep Energy Costs in Check

Jay Godwin photo - 07/31/2015 Location: The Mueller community in Austin, Texas. Caption: Mueller resident Dennis Mick is a Pecan Street program participant. He has solar collectors on his roof and an electric car in his garage. Information about his energy use can be accessed through mobile apps and on the web.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 »

How Energizing Renewables can Spur Carbon Pricing

Photoy Jürgen from Sandesneben, GermanyTo avoid the worst effects of climate change, we must do more to reduce our greenhouse gas emissions. Yet, we still do not have a price on carbon, one of the most prevalent greenhouse gases in the world and the biggest contributor to climate change. Despite knowing that a carbon price creates broad incentives to cut emissions, the current average price of carbon globally (which is below zero, once half a trillion dollars of fossil-fuel subsidies are factored in) is much too low relative to the hidden environmental, health, and societal costs of burning a ton of coal or a barrel of oil.

Policies that comprehensively reform the energy sector—a sector designed around fossil fuels—are necessary even as the price of renewable energy declines. The cost of solar photovoltaics, for example, has declined 80 percent since 2008. Prices will continue to fall, but not fast enough to make a dent in the climate problem.

Policymakers are more likely to price carbon appropriately if renewables are competitive with (or cheaper than) fossil fuels. But reducing the cost of renewable energy requires substantial investment, and thus a carbon price. The best hope of resolution is through controlled policy experiments designed to drive down the cost of renewable power sources even further and faster than in the past five years. Read More »

Critics of Clean Energy in North Carolina: You Got Your Facts Wrong


Critics of North Carolina’s clean energy industry recently bought some radio ads asking state lawmakers who support North Carolina’s clean energy policies to change their minds and turn their backs on this growing industry. These opponents mistakenly argue our state’s clean energy policies burden North Carolinians with rising energy costs that hurt families and cost the state jobs. These claims are baseless.

Yes, energy costs in North Carolina have increased – $40 or $50 per month for many households since 2001. But the growth of renewable energy is not the reason why. Conventional energy sources like coal are getting more expensive, accounting for as much as 84 percent of this increase.

The truth is, renewable energy is helping to slow rising energy costs, saving North Carolina electricity customers $162 million since 2007. And while clean energy continues to grow, so will the savings for our state’s families and businesses – delivering nearly half a billion dollars in additional savings over the next 15 years.
