Commercial Demand Response – An Untapped Resource for the Congested Grid

By: John Gruss, Vice President and General Manager of Enerliance

lobosAccording to the recently released National Climate Assessment, 2012 was the hottest year on record for the continental United States, and experts predict that temperatures are only going to rise. Couple this with an energy grid that is already under severe strain, and there can be no denying we’ve got a serious problem on our hands.

Every year an overstressed electric grid faces increasing challenges to cool and operate homes and buildings. As we approach summer, with heat waves that are growing longer in duration, this crisis could result in energy shortages and blackouts that are not merely a matter of disrupted comfort and lost productivity but are a serious threat to national security and human health.

Transition to Clean Energy will make the U.S. Military More Efficient, Effective, and Safe

When most of us think about military operations, we think of tanks rolling across a desert, large aircraft carriers on the ocean, or long lines of Humvees in convoys. These vehicles, and their missions, take a lot of energy and are part of the large category of “operational energy use.” In fact, 75% of all military energy use is operational.

This operational energy use has created a massive dependence on fossil fuels, resulting in some unintended consequences, which:

  • Cause ships, planes and vehicles, like tanks, to cease operations during refueling. This takes time and keeps the vehicle from completing its mission. Fuel convoys are also prime targets for ambushes and improvised explosive devices (IEDs).
  • Bind the military to a volatile commodity with changing prices and an unstable future.
  • Exacerbate climate change, an issue that U.S. Defense Secretary Chuck Hagel recently called a “threat multiplier.” According to Secretary Hagel, climate change will influence resource competition and “aggravate stressors abroad such as poverty, environmental degradation, political instability, and social tensions.” These stressors will increase the frequency, scope, and duration of future conflicts and, by extension, U.S. military interventions around the globe.  Read More »

Fact: Clean Energy is Working in Ohio

windpowerohioChris Prandoni certainly is welcome to his own opinions, but not his own facts. As the Director of Energy and Environmental Policy at Americans for Tax Reform, Prandoni may favor coal-fired power plants and dislike energy efficiency and renewables, but there’s no doubt Ohio’s clean energy standards are saving consumers money and bringing huge investments into the state.

Prandoni supports S.B. 310, which has already passed the Ohio Senate and is expected to enter the House within the next week, and promises to kill the state’s renewable portfolio standards (RPS) and energy efficiency directives. If Prandoni has his way, and as he points out in his misinformed Forbes op-ed, Ohio would be the first state in the nation to “pare back” its clean energy mandates, but this is not something Ohioans should be proud of.

The Many Benefits of Reducing Carbon Pollution from Existing Power Plants

By: Megan Ceronsky, EDF attorney, and Peter Heisler, legal fellow 

The newly-released Third National Climate Assessment has some eye-opening news about climate change.

The report confirms that if greenhouse gas emissions are not reduced it is likely that American communities will experience:

  • increased severity of dangerous smog and particulate pollution in many regions[1]
  • intensified precipitation events, hurricanes, and storm surges[2]
  • reduced precipitation and runoff in the arid West[3]
  • reduced crop yields and livestock productivity[4]
  • increases in fires, insect pests, and the prevalence of diseases transmitted by food, water, and insects[5]
  • increased risk of illness and death due to extreme heat[6]

Extreme weather imposes a high cost on our communities, our livelihoods, and our lives. The National Climatic Data Center reports that the United States experienced seven climate disasters that each caused more than a billion dollars of damage in 2013, including the devastating floods in Colorado and extreme droughts in western states.[7]

These are precisely the type of impacts projected to affect American communities with increasing frequency and severity as climate-destabilizing emissions continue to accumulate in the atmosphere.

Fossil fuel-fired power plants are far and away the largest source of greenhouse gas emissions in the United States, emitting more than two billion metric tons of carbon dioxide in 2012 — equivalent to 40 percent of U.S. carbon pollution and nearly one-third of total U.S. greenhouse gas emissions.[8] Read More »

Nest’s Promising Results for Reducing Peak Electricity Demand

Nest_front_officialBack in January when Google announced it would spend $3.2 billion to purchase Nest, EDF knew this was a company to watch. The results of three new reports, released today, confirm that controllable thermostats like the Nest Learning Thermostat are both customer-friendly and useful for energy system planners. Moreover, the reports signal that smart devices, such as those Nest manufactures, have potential for generating marked savings for utility customers.

The reports analyze 2012-2013 energy use data gathered from four major utilities across the U.S. that offer Nest energy services programs: Austin Energy, Reliant Energy, Green Mountain Energy, and Southern California Edison.

The first report evaluates the results of Rush Hour Rewards, a demand response service that changes the temperature of the homes of Nest users during energy “rush hours”, or times when demand on the grid is highest. The second examines Seasonal Savings, a program that runs for three weeks and slowly modifies the temperature according to the customer’s behavior (which this smart thermostat is able to ‘learn’ via its built-in motion sensor and understanding of its owner’s temperature preferences). Both operate during times of heavy usage, namely winter and summer. The third report analyzes home energy data of Nest customers more broadly, comparing energy use before and after the installation of a Nest Thermostat. 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 »
