We need fewer politicians and more scientists in our political system to make it doable.

Senator Heinrich: A 100% Clean Energy Grid Is ‘Completely Doable’

Democratic Senator Martin Heinrich is the son of a utility lineman, and one of just a few engineers in Congress.

Clean energy piqued the New Mexico lawmaker’s interest at an early age, while he was building and racing solar-powered cars in college. But for most of his life, he says, it was hard to imagine a world in which renewables could power more than 20 or 30 percent of the electric grid.

Today, Heinrich’s outlook is different. “We can have a future reliable, cheap, resilient grid that is 100 percent powered by clean energy,” he said in an interview on Greentech Media’s Political Climate podcast.

We need to advance renewable energies now so that we won’t need fossil fuel anymore.

Trajectories of the Earth System in the Anthropocene

Our analysis suggests that the Earth System may be approaching a planetary threshold that could lock in a continuing rapid pathway toward much hotter conditions—Hothouse Earth.

Humanity is now facing the need for critical decisions and actions that could influence our future for centuries, if not millennia.

Fossil fuels are dead.

“Wind and solar are set to surge to almost “50 by 50” – 50% of world generation by 2050 – on the back of precipitous reductions in cost, and the advent of cheaper and cheaper batteries that will enable electricity to be stored and discharged to meet shifts in demand and supply.  Coal shrinks to just 11% of global electricity generation by 2050.”

The fight against climate change has seen huge growth in the “new” renewables, wind and solar power, over the past decade, both in developed countries and developing ones.
