Study: Emissions from power plants, refineries may be far higher than reported

By EDF Blogs / Published: March 16, 2017

By Joe Rudek and David Lyon

A new peer-reviewed paper in Environmental Science and Technology suggests that methane emissions from natural gas power plants and oil refineries may be significantly higher than accounted for in current inventories. The report estimates average hourly methane emissions 11 to 90 times higher for refineries, and 21 to 120 times higher for natural gas power plants than those calculated from data provided by facility operators to Environmental Protection Agency’s Greenhouse Gas Reporting Program.

By multiplying total CO2 emitted annually by all US natural gas power plants and refineries (as tallied by EPA) by the methane-to-CO2 emission ratio determined in the study, the authors estimate yearly methane emissions from the nation’s refineries and gas-fired power plants are twenty times higher than currently reported.

Biting the Biggest Apple: New York’s New Plan to Reward Distributed Energy Resources

By Ferit Ucar / Published: March 15, 2017

How do we compensate those who add clean electricity to our shared power grid? This fundamental question has affected the rate at which the U.S. has adopted, deployed, and put into use clean, distributed energy resources such as energy efficiency, batteries, electric vehicles, and rooftop and community solar.

At the core of our new distributed energy electricity system are resources that work better during specific times and weather conditions, and thereby have more value at some moments than others. So, it’s crucial to take time and location into account to properly identify the value of these clean energy resources and how they should be fairly compensated. Solving for price can spur much needed investment in renewable resources and lower the cost of clean energy development, while reducing emissions.

Last week, the New York Public Service Commission (PSC) brought us a step closer to figuring how to fairly compensate distributed energy by issuing a long-awaited order to establish an interim pricing structure that encourages the evolution of distributed energy markets and better aligns with Reforming the Energy Vision (REV), the state’s initiative to build a cleaner, more efficient, and customer-centric electric system.

New Reports Raise Health Concerns About Emissions From California’s Oil and Gas Industry

By Irene Burga / Published: March 13, 2017

For decades communities in California who live close to oil and gas facilities have reported experiencing unbearable odors of gas, headaches, nausea, respiratory problems, and even cardiac complications as a result of the industry’s emissions. The health impacts of oil and gas pollution were made crystal clear last year after a massive gas leak at a Southern California storage facility led to mass hospitalizations and forced hundreds of families to evacuate their homes.

But massive gas leaks like the one at Aliso Canyon aren’t the only cause for alarm. A string of new reports confirm what many concerned communities have known for years: oil and gas emissions from across the entire supply chain can wreak havoc on our health, and are often higher than experts previously thought.

Nation’s Largest City-Owned Utility Uses Equity Metrics to Ensure All Residents Have Clean Energy

By Jorge Madrid / Published: March 10, 2017

This week, the Los Angeles Department of Water and Power (LADWP), the largest municipal utility in the country, released the Equity Metrics Data Initiative (EMDI) “to track, measure, and report on how its programs are provided to all customers and residents of Los Angeles.” This data will help ensure the utility’s investments and programs are reaching all Angelenos.

EMDI is the LADWP’s first effort to use data in the pursuit of equity in planning a clean energy future for all of us. Data gathered during the initiative will be used to create a baseline for measuring the impacts of and access to investment and services from LADWP. These include things like energy efficiency programs, solar incentives, and electric vehicle charging infrastructure ─ tracking how they reach different neighborhoods and customers, particularly those with economic and environmental vulnerabilities.

The Energy Star Program Saves Americans Billions. So, Why Cut It?

By Jim Marston / Published: March 9, 2017

Evidently, President Trump and his environmental protection chief Scott Pruitt are just getting warmed up.

Now they’ve set their sights on one of the most successful and noncontroversial energy-related programs the U.S. Environmental Protection Agency has ever managed – Energy Star, a program that saves consumers more than $30 billion a year.

According to E&E News, Trump’s draft budget encourages the EPA to “begin developing legislative options and associated groundwork for transferring ownership and implementation of Energy Star to a non-governmental entity.”

Translation: Energy Star, you’re dead. Read More »

States Underscore U.S. Methane Momentum, Latest Reason for Canada to Press Ahead

By Drew Nelson / Published: March 8, 2017

U.S. states are accelerating steps to reduce oil and gas air pollution. Just last week Ohio – which has a Republican Governor, and Republican-controlled Senate and House – joined the list of states targeting oil and gas emissions with a new methane policy that requires operators to check for leaks at compressor stations four times a year. Showing that it’s not a matter of politics, but smart policy to require oil and gas companies to regularly inspect for and repair leaky equipment.

At the same time, Canada is developing its own requirements to cut oil and gas methane emissions by 45 percent, an effort that some in industry are resisting over concerns of possible U.S. federal policy changes. But Canada needs to keep its eyes on the states where action has taken hold for good reason.

Methane, a powerful pollutant, has emerged as a key energy and environmental challenge.

Natural gas is mostly methane. When it leaks and is vented from thousands of oil and gas facilities, methane loss to the atmosphere is wasted energy that hurts not only businesses but local economies. Read More »
