Featured Work

A moment of hope on climate: Now what?

With the enactment of the Inflation Reduction Act (IRA), our nation is now finally positioned to achieve its climate targets. Thanks to the IRA, clean energy businesses will benefit from stable, long-term tax incentives like those enjoyed by the fossil fuel sector for more than a century. Tax credits for renewable generation are complemented by new incentives for energy storage, clean hydrogen and domestic clean energy manufacturing.

This PV array has 465 solar panels split between roofs on the southeast and southwest wings of the Denver Museum of Nature and Science. The installation was made possible through a collaboration of Hybrid Energy Group, Partnership for Sustainability, Xcel Energy, and NamastâSolar Electric.

Commerce Department puts solar industry on ice

The U.N. secretary-general recently warned that the world is “sleepwalking into a climate catastrophe.” So it is a tragic irony that the most immediate and sweeping threat to President Joe Biden’s clean energy and climate agenda comes not from the recent push for more fossil fuel development or the intransigence of climate deniers, but from a little-noticed but devastating decision at the Biden administration’s Commerce Department that is bringing America’s booming solar growth to a screeching halt.
