President Donald Trump spoke to chemical workers in Pennsylvania on Tuesday. The speech was supposed to be about energy, but it quickly went off the rails.

Though he was there on an official presidential visit, not a campaign event, that didn’t stop him from using the slur “Pocahontas” to refer to Senator Elizabeth Warren (D-MA), telling the workers to “make sure we win” in the 2020 presidential election, or from joking about the possibility of there being no election at all.

Pushes to prioritize climate change aren't exclusive to the United States.

A crucial aspect of curtailing the climate crisis is lessening the use of energy. Fossil fuels have been used to heat homes for over a century, resulting in an increased worldwide dependence.

Natural gas, which for years has been promoted by the oil and gas industry as the “cleanest” of the fossil fuels, may not be as environmentally friendly as advertised. The United States’ reliance on natural gas as a source of power is only increasing. In 2017, 31.7 percent of U.S. electricity came from natural gas-fired generation, up from 27.3 percent in 2013.

But while natural gas produces fewer carbon emissions than burning coal, the production and transportation of natural gas releases a significant quantity of methane – a greenhouse gas that also contributes to climate change.

GLENDORA, CA - APRIL 22: Solar panels cover the roof of a Sam's Club store that was toured by California Gov. Arnold Schwarzenegger and Wal-Mart officials before their press conference on Earth Day, April 22, 2009 in Glendora, California. Following the tour, the governor and Wal-Mart officials announced that Wal-Mart will expand its solar power programs by adding solar panels on 10 to 20 additional Wal-Mart facilities to generate up to 32 million kilowatt hours of renewable energy every year, the equivalent of powering more than 2,600 homes.

According to the U.S. Energy Information Administration, total solar production in California grew from less than 1 gigawatt in 2007 to nearly 14 gigawatts by the end of 2016. By the end of 2015, the EIA found that California’s utility-scale solar energy production accounted for 52% of the entire nation’s production. That’s no doubt even higher today.

In a discussion on Twitter regarding South Australia’s sweeping rise in energy prices, Elon Musk made one of his grandest declarations to date — and he is known for this sort of thing. Musk claims that he has the ability to construct a 100 megawatt battery storage farm within 100 days. If he fails, he says he will do so free of charge.

It has been one hundred years since Albert Einstein came up with his crowning intellectual achievement--the theory of relativity. That theory, published in 1915, posited that space and time are part of a single, interwoven continuum called spacetime. More importantly, spacetime itself is malleable and “warps” under the influence of matter. What we know as gravity is actually the bending of spacetime by objects with mass.

The world's first solar road, located in the Netherlands, has only been open for six months but is already producing more energy than expected.

SolaRoad has produced over 3,000 kilowatt-hours of energy since opening in November 2014, according to Think Progress. The spokesman for this public-private partnership project, Stan de Wit, spoke of its success in a recent statement:"[w]e did not expect a yield as high as this so quickly."
