EPA: Technology Promotes Environmental Protection

EPA’s National Enforcement Investigations Center is an environmental forensic center. NEIC scientists work with a variety of technologies to monitor, collect data and analyze pollutants in the environment to better understand the threat to human health and ecosystems. Advanced technologies provide tools for scientists to measure, sometimes in near real-time, pollutants emitted from both large and small sources that can adversely affect entire communities.

Boston: Methane Emissions from Natural Gas Infrastructure

Thursday, January 29th, 2015

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA (PNAS)
Most recent analyses of the environmental impact of natural gas have focused on production, with very sparse information on emissions from distribution and end use. This study quantifies the full seasonal cycle of methane emissions and the fractional contribution of natural gas for the urbanized region centered on Boston. Emissions from natural gas are found to be two to three times larger than predicted by existing inventory methodologies and industry reports. Our findings suggest that natural-gas–consuming regions may be larger sources of methane to the atmosphere than is currently estimated and represent areas of significant resource loss.

Going Solar in America: Ranking Solar Value to Consumers

Monday, January 26th, 2015
Overall City Rankings

Most Americans are unaware of the true financial value of solar today. Seen by many as a technological luxury, solar energy is not seriously considered as an option by most homeowners in the U.S. However, our analysis shows that, in 46 of America’s 50 largest cities, a fully-financed, typically-sized solar PV system is a better investment than the stock market, and in 42 of these cities, the same system already costs less than energy from a residential customer’s local utility…So why aren’t more Americans investing in solar? There is a clear information gap, and with this report, we intend to open the eyes of average homeowners by showing that solar can generate both significant monthly savings and long-term investment value, and not infrequently, cost less than energy from some of America’s largest electric utilities.

Wind Energy Saves Consumers Money

Monday, January 12th, 2015
Wind Energy Chart

AMERICAN WIND ENERGY ASSOCIATION
Wind energy’s consumer benefits stem from wind energy’s fuel price stability. Wind is one of the few energy sources that offers perfect fuel price stability that can be locked in up front, as wind’s fuel cost will always be zero. For all other major conventional sources of electricity, fuel prices cannot be locked in for the long term and are often set by the spot market. The costs of these fuel price increases and risk are passed directly on to consumers through their electric bills. In contrast, wind energy is more like a fixed-rate mortgage, locking in the fuel price for the life of the power plant.

Our Energy Tomorrow: The State of American Energy

Friday, January 9th, 2015

America now occupies a position of energy leadership that was unthinkable a short time ago. Gone are the days of uncertainty and concern over having the supply of energy we need, when we need it. Today, the United States is the world’s top producer of natural gas, the world’s leading refiner of petroleum products, and very soon could be the leading producer of oil…But this is only part of America’s larger energy story. The United States is in the midst of a new era in domestic energy abundance characterized by rising use of renewable energy and increased oil and natural gas production that is strengthening our economic outlook and enabling America to emerge as a global energy superpower.

Interactive Map: Where Do Trains Carry Crude Oil?

Crude Connections: Where Do Trains Carry Crude Oil?

Rail fans can still spot coal-laden boxcars from coast to coast, but today’s locomotives are increasingly likely to pull tankers full of crude oil. Largely stemming from the fracking boom in North Dakota, crude oil transportation by rail has reached unprecedented heights in past years. In response to a growing number of accidents–some on an apocalyptic scale, as in Lac-Mégantic, Quebec–ProPublica assembled an interactive map to let you know whose tankers carry crude oil, where they’re coming from, and where they’re going.

More Wind, Less Warming

Figure ES-1. A Path to 30 Percent Wind Electricity

ENVIRONMENT TEXAS
American wind power is already significantly reducing global warming pollution. In 2013 alone, wind power averted 132 million metric tons of carbon dioxide emissions – as much as would be produced by 34 typical coal-fired power plants. But with the United States and the world needing to move toward a future of 100 percent clean energy in order to prevent the worst impacts of global warming, America must do much more.
