The second half of the clean energy equation is transmission. ... which require 70 percent renewable energy by 2030 and a zero-emissions grid by 2040. ... Running towards the post-COVID light.

Though the energy-mass equation might appear simple, there are some special cases that appear to challenge its assumptions. Take the case of photons, for example. These particles, which represent ...

It’s Thursday, April 28, and inefficient light bulbs are on their way out. Incandescent light bulbs had a good run. But roughly 140 years after they were patented by Thomas Edison, the ...
