The inevitable challenges of energy transitions
The start of the 20th century, marked the entry of new sources of energy such as oil and gas. However something else started to take shape. In 1927, while coal was still claiming its lion’s share of total primary energy consumption, the first commercial wind turbine was sold on the open market which arguably marks the start of the renewables’ revolution. The Hoover Dam came in 1935 while 1958 was the year in which the first US satellite was powered only by solar energy.
Today, almost 100 years into this journey, the share of primary energy from renewable sources sits at 13.5% globally, and under the Net Zero scenario renewables may reach 65% in global primary energy as soon as 2050.
