Coal is a dirty energy source. It pollutes our environment with toxins, produces a quarter of U.S. global warming emissions, and accounts for a whopping 80 percent of all carbon emissions produced by power generation nationwide.

Smart Energy Solutions: Decrease Coal Use

Coal is a dirty energy source. It pollutes our environment with toxins, produces a quarter of U.S. global warming emissions, and accounts for a whopping 80 percent of all carbon emissions produced by power generation nationwide.

When we burn coal for electricity, we place our health, our environment, and our planet at risk. It’s time to reduce our dependence on this polluting energy source.

There are nearly 600 coal-fired power plants operating in the United States today, producing almost half of the nation’s electricity. To decrease our reliance on coal, we must shut down the oldest and dirtiest coal plants and replace them with reliable and clean energy sources.

UCS experts work to analyze practical, cost-effective strategies for lowering America’s coal use—and have consistently demonstrated that closing down the dirtiest coal-fired power plants would not adversely effect the reliability of our electricity supply, nor would it significantly increase the cost of electricity for consumers.
Do We Need New Coal-Fired Power Plants?

NO. If we increase renewable energy and improve energy efficiency, we can completely eliminate the need for new coal-fired power plants and shut down the oldest, dirtiest plants without adverse effects to our electricity supply.

America's Costliest Coal Plants are Ripe for Retirement

A significant number of U.S. coal-fired power plants are old, inefficient, and no longer economically competitive. They are ripe for retirement — it simply makes no financial sense to keep them running when cheaper, cleaner alternatives are available.

Investing in Coal Makes No Economic Sense

Utilities and other electricity producers are poised to invest heavily in retrofitting old coal-fired power plants or in building new ones. Current economic, technological, and policy trends make such commitments exceedingly risky, both from a financial and environmental perspective.

The costs of coal go beyond just its environmental impacts. Coal also incurs substantial economic costs for the states that rely on it most, especially when they import large amounts from other states or foreign countries.

We Can Burn Less Coal—and Burn It Cleaner

Coal will remain part of our electricity mix for several decades as we transition to a clean energy economy. In the interim, we can minimize the environmental impact of coal-fired power plants by adopting technologies that significantly reduce coal pollution and global warming emissions.

Smart government policies can encourage the deployment of this technology, as well as support investment in more advanced emissions-reduction technologies like carbon capture and storage.

Coal Threatens Climate Policy in the Northeast

The Regional Greenhouse Gas Initiative caps carbon dioxide emissions from power plants in 10 Northeast states and marks an important milestone in the country’s response to climate change. Yet that pioneering effort could unwittingly contribute to greater use of coal elsewhere.

Thanks J.L. Regardless of how we over 7 billion humans get our external and internal energy, we trample and disrupt eco-systems and cause extinctions throughout the planet, in our quests to fill our 7 billion plus voracious appetites. Too many of us demanding too much of this world. Coal, solar, wind, nuclear, damning water, tidal, all take more from the planet than can be given back, and recycled in positive ways for a near positive future.

I can't stand Liberals like Rev. Pat Robertson who are all for deep-earth drilling! Lin is right; we're 'ripping up snort' with all the violence we're producing! Thnx J.L. A.!!

I've heard Pat Robertson called many things but liberal? I think he would stroke out over that.

My home town has canceled all coal contracts and is building a massive solar array. Each community needs to look for what is best for their area, for some it may be combinations of wind, solar or other alternatives. The future will look back at us wonder why we were so short sighted.

Now what am I saying - the new coal and gas are clean fuels - that is if you believe the advertising.
