Renewables

Interesting read from Rebecca Solnit on the renewable energy revolution underway.

“Today, most energy is wasted along the way. Out of the 606 EJ [exajoules] of primary energy that entered the global energy system in 2019, some 33% (196 EJ) was lost on the supply side due to energy production and transportation losses before it ever reached a consumer. Another 30% (183 EJ) was lost on the demand side turning final energy into useful energy. That means that of the 606 EJ we put into our energy system per annum, only 227 EJ ended up providing useful energy, like heating a home or moving a truck. That is only 37% efficient overall.”

When All You Have Is a Hammer...

Australia has some of the biggest natural gas reserves in the world, so when looking around for something to juice the post-C19 economy, what better solution than to push gas as the best option, despite the fact that it’s not a climate friendly as people think.

Both Woodside and Santos have resisted the push, and argued that gas is a “clean” fuel and part of the climate solution. Like Taylor, they claim Australian gas exports are an environmental good as they reduce coal in Asia. Neither the government nor industry have provided evidence to back this up, and officials have acknowledged the competition in Japan – still Australia’s biggest gas market – is increasingly with zero emissions nuclear and renewable generation.

Andrew Grant, head of oil, gas and mining with London-based financial thinktank Carbon Tracker, says the global view of gas has flipped from it being seen as a cleaner fuel than coal, to it being the second-least desirable source of electricity.

Apparently it’s the future, though that’s not supported by any evidence - it’s just a useful way of trying to force fracking upon the states against their populations’ will.
