A Dozen Nations Have Entered Solartopia While Trump Leaves U.S Industry to DieA dozen nations of the world and two US states have officially entered Solartopia. They all now generate more electricity with renewable sources than theywww.counterpunch.orgAnd so far, nuclear electricity proliferation to Iran alone has cost the U.S. $37.5 bil, with another $87 bil being requested www.bbc.com/news/article... Yet, some pretend nuclear electricity is cheap and others want to proliferate small reactors to the 170 countries that don't have weapons.

Trump approves US-Saudi civil nuclear energy agreement, officials sayPresident Trump has approved an agreement with Saudi Arabia to partner on developing the Kingdom's civil nuclear energy program, according to two U.S. officials.abcnews.comThe Canadian wildfires will hereafter be known as the #TrumpWildfires. Fueled by climate damage exacerbated by Trump's policies to promote more climate-warming air pollution that lengthens dry seasons and dries out wood, creating conditions for disastrous wildfires.
Mark Z. JacobsonWhen will you stop paying fossil+bioenergy companies to poison our air, Trump? 100,000 Americans die from fossil+bio air pollution yearly You take money from wind+solar, which eliminate deaths, & give it to fuel companies to kill more+increase climate damage thus fire damage x.com/marlene4719/...

It’s time for the Clean Energy World Cup!foresightmedia.comEven the untrained eye can see that intermittent WindWaterSolar is closer to matching demand, particularly summer peak demand, than is baseload nuclear, year after year after year. Nuclear stays flat, except when half of it is down 1-3 times per year. WWS rises in summer.

Too bad he doesn't look at data US & world data show that more WindWaterSolar correlates with lower electricity prices. More fossils, nuclear & biomass correlate with higher prices Applies to the world web.stanford.edu/group/efmh/j... and US states web.stanford.edu/group/efmh/j... @atrupar.com
