Imagine you’re trying to lose weight. If you step on the scale once a month, how can you possibly know how each of your daily decisions affects the number? Weighing yourself every day would be a step up, giving you a much clearer picture of the effects of each day’s choices. Now imagine the potential results if you could access real-time data – if you were able to see just how many calories were in each food you picked up, as well how much energy you were exerting at any given moment.

Thanks to a meta-analysis on behalf of the American Council for an Energy Efficiency Economy (ACEEE), we can now see that access to this kind of granular, real-time data on electricity use leads to significant household electricity savings.

Survey highlights importance of timeliness and granularity

The ACEEE survey aggregates multiple studies designed to evaluate the effectiveness of different types of electricity customer feedback from the past 20 years, including 61 trials from around the world: 33 from the U.S., 13 from Europe, 9 from Canada, and 3 others. Such a diverse pool allows us to draw important conclusions about consumer energy use habits while controlling for variations in culture, climate, and energy use patterns. The results are displayed in the graph below. Read More »

Elon Musk's Love-Hate Relationship with Texas

For months now there has been much secrecy and mystery surrounding the location of electric car revolutionary Tesla's new $5 billion Gigafactory. The factory will supply cheaper batteries for the company’s Model 3 electric car and will be large enough to manufacture more lithium-ion batteries than the entire industry produces now. Due to its sheer scale, the factory is expected to reduce the cost of batteries by almost one-third and create close to 7,000 jobs directly and thousands more indirectly.

Amidst all the rumors abounding, closed door meetings, and tax break wars, I wrote about Tesla’s search for the perfect factory location – of which Texas was in the running. Despite Tesla breaking ground near Reno, Nevada a few weeks ago, there was still speculation about where the Gigafactory might be located, and Texas' chances remained somewhat alive.

But no more. Tesla indeed confirmed that Reno will be the home of the Gigafactory. This is great for Nevada’s economy, but as a Texan, it still feels like a bit of a blow – though I’m not surprised.

While Texas Governor Rick Perry personally lobbied for the Gigafactory to make its home in Texas, it doesn’t help that he’s at the helm of a state hostile to clean energy, despite leading the nation in wind power. Although I’m hopeful that future clean tech endeavors will come to Texas, the existing status quo needs to change to combat this hostility.   Read More »

McKibben and EDF Agree: Plugging Methane Leaks "A Huge Priority"

Methane is flared from a natural gas well site.

Methane is flared from a natural gas well site.

Bill McKibben is at it again—using his formidable analytical and rhetorical skills to challenge comfortable climate assumptions. In this case, the author and activist puts the heat on politicians, including Barack Obama and Hillary Clinton, who argue that natural gas can be a “bridge fuel” to a low-carbon energy future.

Since natural gas emits half the carbon of coal when it’s burned, supporting it gives politicians a way to position themselves as both pro-energy and pro-climate. But writing in Mother Jones, Bill questions whether switching from coal- to natural gas-fired electric generation brings any climate benefit at all.

Because natural gas is mostly methane, a potent greenhouse gas, he points out that if enough uncombusted methane is leaking from the natural gas supply chain, natural gas may be even worse for the climate than coal.

We couldn’t agree more. Read More »

Utility 2.0: New York Electricity Market Should Allow Third Parties to Compete

The New York Public Service Commission (Commission) has embarked on the landmark Reforming Energy Vision (REV) proceeding to design a new business model for electric utilities. Today’s business model allows utilities to earn revenues based on how much money they spend to supply and deliver electricity. Under the new model, utilities will earn revenues based on the value of services they deliver to customers and the environment.

Currently, utilities dominate the electricity service market, limiting customer access to the full range of products and services otherwise available in a truly open market. One focus of the proceeding is to remove the barriers preventing third parties, such as retail electric suppliers, solar energy companies, or smart meter providers, from fully participating in the energy market. Allowing full participation by third parties would lead to increased innovation and fuel the development of new products and services. Read More »

California Clean Energy Bill Could Open Door for Homeowners and Small Businesses

Governor Brown has the opportunity to make energy-saving upgrades possible for families and small business owners by signing Assembly Bill 1883 (Nancy Skinner- Berkeley). This bill would significantly lower the cost of Property Assessed Clean Energy (PACE), a tool which enables property owners to take advantage of energy efficiency and rooftop solar PV for their homes or buildings with no money down, allowing them to pay off the investment over time through their property tax bill.

AB 1883 would streamline the PACE process and drive down the fixed transactional costs associated with commercial projects. Lowering these transaction costs is especially important for small businesses because high transaction costs can reduce the economic viability of the smaller energy upgrades that small business typically need. AB 1883 also incorporates new options for financing rooftop solar PV through PACE, which will enable a greater number of homeowners and small businesses to qualify for cost-saving solar PV contracts.

Sprung a Leak? Smart Water Meters to the Rescue

Source: freshserviceinc.com

A few months ago I logged into my online utility account and noticed it was more than twice the amount I usually pay, all of the excess going to water. Given the kind of work I do, I scour my bill every month, comparing electric and water usage month-to-month and over the course of the year. We are water and electricity savers in our household, so what on earth could this spike be?

I immediately called the City of Austin, and they sent someone out to check the meter. Nope, nothing on that end. Then we brought in a plumber, who spent many hours and many of our dollars searching and found a leak in the toilet. By the time we went through all of that and got the toilet fixed, we had to pay our enormous bill plus the plumber’s bill. Why should I have to go through that rigmarole just to find a leak?

Wouldn’t it be easier if a smart water meter could send my utility and me a message the moment the toilet starts leaking?

Unfortunately, water infrastructure in this country is sorely in need of a reboot. The American Society for Civil Engineers gave the U.S. drinking water infrastructure a grade of a “D” in its 2013 Report Card for America’s Infrastructure, stating there are 240,000 water main breaks per year. And we’re still using antiquated “technology” in much of the sector. Read More »

Changing Light Bulbs Can Mean a Wealth of Energy Savings

By: Karunakaren MH, student at the Thunderbird School of Global Management

edfcc - led light bulbsA few months ago, I traveled halfway across the world from the bright, hot tropical beaches of south-east Asia into a gloomy, chilly Chicago summer to begin my journey as an EDF Climate Corps fellow. A week before I started at Associated Materials, a thunderstorm flooded the entire ground floor of the corporate office, and the place needed to be completely restored. What a cliché! Because of how quickly they recovered, I arrived at the office knowing that its resilience to adversity and commitment to energy efficiency goals would mean I had a great summer ahead of me.

Associated Materials (AMI) is a vertically integrated company in the exterior building products industry with 11 manufacturing locations and over 120 distribution centers catering to the North American market. It spends about $15 million annually on energy utilities and, this summer, hired two EDF Climate Corp fellows to look for opportunities to reduce energy costs. I worked on the manufacturing locations and my colleague, Vinnakota Krishna, looked at the supply centers. Read More »

Clean Power Plan to Reward Texas, not Wyoming Coal-Backers

Source: Aurora Lights

Chronicle readers would be forgiven if they opened their papers last weekend and thought it was 2005. That’s because the Koch brothers-funded Texas Public Policy Foundation published an editorial that echoed the pro-coal rhetoric we heard nearly 10 years ago when then-TXU wanted to build new power plants across Texas that would burn Wyoming coal.

Sure, this weekend’s piece had a different news hook – the new Clean Power Plan that will require Texas to reduce carbon emissions from power plants like every other state. But TPPF’s conclusion was the same: better, cleaner technology is bad and coal is king. As Yogi Berra would have said, “It’s like déjà vu all over again.”

Texas is the number one carbon emitter in the U.S. and power plants, together, are the largest emitters. Our state represents close to 10 percent of the entire nation’s carbon emissions. The Clean Power Plan will simply require Texas to adhere to the rules all other states have to follow. I love Texas more than the average person, but I don’t think we should get special treatment simply because some of our energy companies doubled-down on fossil fuels. And I certainly don’t think we should rely on Wyoming coal when Texas is the nation’s energy powerhouse. Read More »

2014 is shaping up to be the year of the energy-water nexus. First, the United Nation’s World Water Day centered on this topic. Then, the U.S. Department of Energy released a 250-page report on the energy-water nexus and indicated that it will be included in its Quadrennial Energy Review. And, this week, the biggest international water conference, World Water Week, is taking on the nexus.

Held every year in Stockholm, Sweden, World Water Week is led by the Stockholm International Water Institute (SIWI) and serves as a platform for over 200 collaborating organizations and 2,500 participants from 130 countries around the world to discuss global water and development issues.

In choosing the energy-water nexus as this year’s theme, SIWI and its supporters are affirming – on a global stage – what policy experts have been saying for years: energy and water are inextricably linked, and the best way to set the energy-water system on a sustainable course is to plan for both resources holistically.
