On the contrary, coal provides roughly half the nation’s electricity—far more than any other source of power—and our coal use has nearly tripled since 1960.Our coal use will continue to expand if the power industry succeeds in building the many power plants it has proposed for construction. While the direct price of electricity from the nation’s aging fleet of coal plants may be low, it doesn’t reflect the staggering and lasting costs of coal-related air and water pollution, mining accidents, permanently altered landscapes, and, most importantly, climate change.

Many people think coal represents a bygone way of life and that America has moved on to safer and cleaner energy sources.

MAKE SURE YOU ASK WHAT DENSITY EPS FOAM THE MANUFACTURER WILL PROVIDE.

It is often not easy finding this information unless you ask.

This technology could become an important part of the battle against global warming, but it remains to be seen whether it will work at a commercial scale and at what cost.

Meanwhile, a 2009 UCS study found that we can dramatically reduce our coal use—and all the environmental and social costs associated with it—while saving energy consumers money with policies that aggressively promote energy efficiency and renewable power.

The blowing agent Pentane is a VOC while it is mostly consumed in the manufacturing process, some studies have shown approximately 30% of the blowing agent remains with the panels.

And green building experts have long noted other health concerns with Polystyrene insulation, as noted here by Environmental Building News.

Even the newest proposed plants – which would cost far more than existing plants—would have major impacts on air and water quality, and almost the same mining and climate impacts as existing plants.

Technology is evolving that has the potential to substantially reduce coal’s contribution to global warming by capturing carbon emissions before they are emitted.

Coal was formed when dead plant matter submerged in swamp environments was subjected to geological forces of heat and pressure over hundreds of millions of years.
