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.”
