Home Is Where the Smart Is: First-of-its-Kind Study Reveals Importance of Smart Technology and Low-Water Clean Energy

By: Kate Zerrenner and Dustin McCartney, Senior Data Analyst, Pecan Street

Have you ever thought about how much water your dryer needs to dry your clothes? (And no, I don’t mean your washing machine.)

Every appliance in your home has a water intensity, or the amount of water needed to make and send the electricity that powers it. On the flip side, all water – like in your faucet, toilet, and irrigation system – has an energy intensity, the amount of electricity needed to treat, distribute, or heat the water. Chances are, you probably haven’t given much consideration to the water intensity of your home energy, or the energy intensity of your water. There hasn’t been any data at the household level – until now.

Environmental Defense Fund (EDF) recently teamed up with Pecan Street, Inc. to examine these combined metrics in a new study. Pecan Street, a research group running the most extensive energy-tracking in U.S. history, analyzed the energy and water costs of a group of Austin homes and their appliances.

By gathering granular data on how much energy and water households use, as well as their associated energy and water intensities, this study reinforces the need for smart technology to help us better understand and manage energy and water. Moreover, in order to safeguard water supplies, the analysis demonstrates the importance of powering our lives with low-water clean energy resources. Read More »

Talking TERP– The Texas Approach to Clean Air (Part 1)

Texas is home to many unique things – from the iconic Cadillac Ranch in Amarillo to the Eiffel Tower in Paris (Texas), we tend to do things a little differently from the rest of the country.

The same is true with how the state has decided to deal with an air pollution problem that was affecting many areas in the state years ago. Instead of requiring specific actions from businesses and others whose operations create air pollution, our business-friendly state took another tactic – we created a voluntary incentive program to pay for emission reductions.

It’s called the Texas Emissions Reductions Plan – or TERP for short. And it has worked surprisingly well. Read More »

Texas Companies Among Winners of EPA Award for Sustainable Freight Transport

trucks flickrEPA just announced the winners of the 2016 SmartWay Excellence Award for sustainable freight transport.

44 companies — out of more than 3,500 partners in the program – were honored for their accomplishments in freight supply chain environmental performance and energy efficiency.

This year’s well-deserved accolades went to 43 truck carriers, seven shippers and one barge carrier – including some SmartWay partners in Texas.

The awards demonstrate that environmental stewardship and economic success go hand in hand, and are an example of EPA’s commitment to recognizing companies that achieve those “win-wins.”  Read More »

Which Came First: Clean Trucks at Ports or a Port Clean Truck Program?

trucks-pixabayThe classic “chicken or the egg dilemma” is often used to talk about cause and effect. Although this question is usually posed as a philosophical examination of some obscure topic, we now have a clear case for true causality: port clean truck programs result in cleaner trucks at ports.

Last week, the Port of New Orleans joined the growing list of ports who have launched formal clean truck programs to encourage trucking companies to replace older, more polluting trucks with newer trucks with fewer emissions. Environmental Defense Fund (EDF) supported the Port of New Orleans’ efforts to develop their “Clean Truck Replacement Incentive Program” (Clean TRIP), which will be funded from the EPA’s Diesel Emissions Reduction Act Program. The funding will assist 20 truck operators in replacing their dirtier diesel trucks by offering up to $35,000 or 50 percent of the cost of a 2012 or newer truck. In addition to the immediate opportunity to reduce emissions from the first 20 trucks, the port will also be able to incentivize more truck replacements in the future, by pursuing additional grants or developing other innovative funding approaches.

The Port of New Orleans joins the Port of Houston as the only two ports on the Gulf Coast with clean truck programs. The efforts in Houston have been successful (and cost-effective, according to a peer-reviewed scientific study conducted by EDF authors) in reducing smog-forming pollution and cancer-causing diesel particulates, but we estimate there are still more than 2,500 trucks operating at the Port of Houston that would benefit from replacement.

Panama Canal Expansion – Panacea or Problem for Ports in Texas?

Everything is bigger in Texas, they say. Now, with the expansion of the Panama Canal this summer, we may start to see bigger ships in some Texas ports, too. These bigger ships would represent more business for Texas, but there could be a downside. Since these ships have huge engines that emit dangerous pollutants, we could see – and breathe – dirtier air. That’s why it’s so important for us to carefully manage these changes.

In late June, the first post-Panamax ship traveled through the newly-expanded Panama Canal, signaling a new era for mega-containerships and other super-sized vessels that can carry up to three times as much cargo as before. (“Panamax” was the term for the Panama Canal Authority’s size limit for ships traveling through the canal, The new mega-ships are sometimes called “Neopanamax” vessels.)

The expansion of the Panama Canal means that the near monopoly held by west coast ports, like the Ports of Los Angeles/Long Beach and others, on container trade from Asia may be ending. Instead of offloading cargo in southern California and relying on trains and trucks to transport goods to inland regions in the U.S., shippers will now be able to offload containers from Asia at U.S. ports on the Gulf or East Coast — taking advantage of potentially lower shipping costs and improved economies of scale.

2 Ways El Paso Just Upped Texas’ Solar Game

SolarPanelArrayThe city of El Paso has many nicknames, but “The Sun City” is probably the most well-known. After two important energy updates this summer, West Texas’ largest city has even more reason to call itself that.

First, El Paso Electric, the public utility that serves nearly half a million customers, reached a major milestone: It is now officially 100 percent coal-free and has pledged to increase its solar investment. Second, the utility agreed to eliminate its proposal that would have resulted in different electricity prices for customers with solar panels at their homes. Such a pricing structure would have placed an unnecessary burden on El Pasoans with solar.

Sunny El Paso has incredible potential for solar power, and both of these developments are positive signs for the city’s clean energy future. Let’s take a closer look at each.
