Powering Texas: Big, Clean, Market-Driven Changes are Already Underfoot

By: Peter Sopher, policy analyst, clean energy, and Sarah Ryan, clean energy consultant

wind-364996_640 pixabayOver the past century, the electric grid in the United States has experienced only minor changes. There is evidence, however, the power sector is changing. We are moving away from traditional coal generation and toward alternative, cleaner energy sources. And despite our state being primarily known for oil and gas, Texas is no exception.

In fact, Texas’ electricity sector has been trending cleaner over the past decades, driven by deregulation of the electricity market, the development of the massive highway of transmission lines built to carry West Texas wind to cities throughout the state – the Competitive Renewable Energy Zone (CREZ), and technological progress. Basically, once the market was opened up to competition, the more economic options – which also happen to be cleaner – began to gain a foothold. And there’s no stopping this train.

Where we are and where we’re going

To start, the declining use of fossil fuels to power our lives is perhaps the most significant change in Texas. As shown in Figure 1 below, fossil fuels’ (coal and gas’) proportion of the state’s electricity generation mix shrunk from 88 percent in 2002 to 82 percent in 2013. Read More »

How Does the Investor Confidence Project Work? Check Out Our New Factsheet

By: Max Wycisk

ICP Logo newestThe Investor Confidence Project (ICP), Environmental Defense Fund’s (EDF) signature buildings efficiency finance program, is sometimes hard to explain in a nutshell. Ultimately, the program aims to create confidence among investors financing energy efficiency projects by standardizing how projects are designed and implemented across the commercial buildings sector. But how do we get from the origination of a project to a successful return on investment?

Our new ICP factsheet aims to answer this question and more. We’ve even developed this helpful infographic depicting a step-by-step process for using the ICP system: Read More »

FERC, Grid Operator, Others File Supreme Court Briefs in Demand Response Case

The Federal Energy Regulatory Commission (FERC), a grid operator, states, and other parties just filed briefs with the U.S. Supreme Court in a case that could decide whether Americans have access to low-cost, clean and reliable electricity.

The case, EPSA v. FERC, revolves around demand response, a resource that helps keep prices low and the lights on – and does so while also being environmentally friendly.

In 2013, for example, demand response saved customers in the mid-Atlantic region close to $12 billion. And during the polar vortex, which threatened the North-East with freezing cold in 2014, the same resource helped prevent black-outs.

The clean energy rule at issue in this case is called FERC Order 745. EDF has been writing about this demand response case throughout the past year. We’ve been fighting for low-cost demand response and we’ll keep fighting in the Supreme Court.  Read More »

FirstEnergy Clings to the Energy Past

800px-Power_lines_(8618709561) flickrAll around the country, we are seeing signs of innovation when it comes to the electricity industry. The state of New York is performing a comprehensive review of related technologies and business practices, Illinois is modernizing the electric grid and empowering customers to save energy by creating transparency around smart meter data, and the wind industry in Texas continues to set new records. The U.S. grid is truly beginning to evolve from the system Thomas Edison created 100 years ago, moving toward a more flexible grid that runs on clean, renewable resources.

Yet some players – with significant revenue and power – are not on board. FirstEnergy, the Akron-based utility giant, has been clinging to the past and waging war on clean energy in Ohio, as I explain in my op-ed published today in the Akron Beacon Journal. The Beacon Journal is the hometown newspaper of FirstEnergy’s headquarters. Read More »

Oil & Gas Industry Mangles More Facts, Turns EDF Study Results Upside Down

Here we go again.

A new set of peer-reviewed scientific papers pointing to 50 percent higher than estimated regional methane emissions from oil and gas operations in Texas were published this week. And like clockwork, the oil and gas industry’s public relations machine, Energy In Depth, proclaimed that rising emissions are actually falling, and that the industry’s meager voluntary efforts are responsible.

This is, of course, wrong on both counts. In fact, it’s a willful misrepresentation of the findings.

First, the assertion that emissions are going down is flat wrong. EPA’s latest inventory released in April reports that in 2013 the oil and gas industry released more than 7.3 million metric tons of methane into the atmosphere from their operations—a three percent increase over 2012—making it the largest industrial source of methane pollution. So much for those voluntary efforts. Read More »

New Research Finds Higher Methane Emissions, Reduction Opportunities in Texas’ Barnett Shale Region

Methane emissions from vast oil and gas operations in the densely populated Barnett Shale region of Texas are 50 percent higher than estimates based on the Environmental Protection Agency’s (EPA) greenhouse gas inventory, according to a series of 11 new papers published today in Environmental Science & Technology.

The majority of these emissions are from a small but widespread number of sources across the region’s oil and gas supply chain. These emissions come from the sort of leaks and equipment malfunctions that are relatively easy to prevent with proper and frequent monitoring and repair practices.

The sprawling Barnett region, fanning out westward from the cities of Dallas and Fort Worth, contains about 30,000 oil and gas wells, 275 compressor stations, and 40 processing plants. It is one of the country’s largest production areas, responsible for 7 percent of total U.S. natural gas output.
