National Guard responding to flood emergencies.
When the U.S. military calls climate change a “threat multiplier” and “a serious threat to national security,” it makes anyone stand up and pay attention. From direct land impacts and food and water shortages, to the displacement of millions of people, climate change is not taken lightly by our armed forces.
Earlier this week, two military experts, Lt. Gen. Ken Eickmann (USAF, Ret.) and British Rear Admiral Neil Morisetti (Royal Navy, Ret.), testified at a Texas House International Trade & Intergovernmental Affairs Committee Hearing and later at an event hosted by the Robert S. Strauss Center for International Security and Law and the British Consulate-General University at University of Texas' LBJ School. As a senior research fellow at the University of Texas at Austin's Energy Institute and Former UK Foreign Secretary Special Representative for Climate Change, Eickmann and Morisetti, respectively, bring a level of trust and confidence to this issue, disarming the politics, if just for a moment, and replacing it with pragmatic duty.
Eickmann and Morisetti’s message was loud and clear: We need to diversify our energy options and shift more toward a clean energy economy. The potential for Texas is boundless. Read More
Science is a process of asserting a hypothesis, collecting data, presenting results, and then having those data and results tested by other researchers. Peer-reviewed journals routinely allow for comments on papers and responses by the authors precisely in order to ensure that knowledge evolves and the dialogue is part of the public scientific record.
People paying close attention to the growing body of research on methane emissions from the oil and gas industry may note of a recent exchange in Environmental Science & Technology (ES&T) between Mr. Touché Howard and a team of scientists lead by Dr. David Allen of the University of Texas. The studies by Allen et al. are among of a group of 16 studies on methane emissions from the natural gas supply chain being coordinated by Environmental Defense Fund. Read More
Each year, the nation wastes an estimated two trillion gallons, or about 14 to 18 percent, of its treated water through leaks alone. That’s a lot of water – enough to fill over three million Olympic-size swimming pools.
We know smart water meters are a critical component to better understanding our water use, but smart meters are only one part of the equation. What we really need is a smart water system.
A more intelligent system could not only help water providers and people better understand their use and how to adjust their behavior accordingly, but it could make the entire treatment and delivery of water more efficient. Plus, system-wide data could make daily water use and associated cost accessible – not an end-of-the-month billing surprise – enabling residents to make more informed decisions and utilities to waste less water.
Energy and water are connected, but they may need different solutions
The energy sector has learned a lot about the smart grid, and put a great deal of its research into practice. And, compared to the water sector, the electricity sector is pretty far along with its smart meter roll-out and understanding of all the information points across the system. For instance, in Texas, more than 3.5 million smart water meters have been installed, compared with approximately 17 million electric smart meters. But, while much of the smart electric grid findings are valuable in relation to the water sector, there are clear differences. Read More

You don’t have a south-facing roof. You have too many trees in your yard. You may not be committed to staying in your house for the next ten to fifteen years. Or maybe you rent, or don’t have the upfront money to install.
These may be some of the reasons why you can’t go solar. You are not alone.
In fact, only 22 to 27 percent of residential rooftops are suitable for installing a solar PV system, due to structural, shading, or ownership issues, according to the National Renewable Energy Laboratory. These effects are even more prominent in densely-populated, urban areas, like Chicago, where viable project siting is limited and renters account for more than half (55 percent) of housing.
But in a new utility world of flowing electricity data and layered intelligence, we shouldn’t limit participation in the rapidly growing solar market to those inconvenienced by circumstance. We need to shift our thinking of distributed solar from the individual to the community. Read More
Each month, the Energy Exchange rounds up a list of top clean energy conferences around the country. Our list includes conferences at which experts from the EDF Clean Energy Program will be speaking, plus additional events that we think our readers may benefit from marking on their calendars.
Top clean energy conferences featuring EDF experts in March:
Mar 6-8: Global Clinton Initiative University Meeting (Miami, FL)
Speaker: Miriam Horn, Special Projects
- President Clinton and Chelsea Clinton will host the eighth annual Global Clinton Initiative University (CGI U) Meeting at the University of Miami. The meeting will bring together more than 1,000 innovative student leaders to make Commitments to Action in CGI U's five focus areas: education, environment and climate change, peace and human rights, poverty alleviation, and public health. Through the CGI University Network, The Resolution Project, and other opportunities, over $900,000 in funding opportunities will be available to select CGI U 2015 students to help them turn their ideas into action.
With time-variant pricing, people can choose to run their dishwashers at times of day when electricity is less expensive.
Today, most residential electricity customers are charged the same price regardless of when the electricity is actually being used. Charging customers a uniform price for electric service looks a bit like buying groceries by the cart instead of by the items purchased (e.g., apples versus filet mignon) – simple, to be sure, but so riddled with inefficiencies that no one would actually propose operating a supermarket that way. A cartful of filet mignon may weigh the same as a cartful of apples, but the value of these items and the cost of bringing them to market is drastically different. Similarly, electricity costs differ depending on the time of day power is produced and delivered.
Time-variant electric pricing addresses this issue by charging customers different prices depending on when electricity is used, reflecting the true costs of producing and delivering electricity. This gives customers greater control over their electricity bills by allowing them to reduce their energy use at higher-cost times. A recent blog post by my colleague, economist Beia Spiller, explained how time-variant electricity pricing can benefit customers, utilities, and the environment, and described several different types of time-variant pricing.
Given its compelling economics, one would think time-variant pricing would be widespread. Part of the reason it’s not is sheer inertia, but there’s more to it than that. Read More
