Overview

Energy is vital for a good standard of living, and affordable sources of power that do not cause climate change or pollution are crucial. Renewable energy is recognized as providing the answer, with countries from around the world deciding at COP28 in 2023 to aim to triple the global renewable energy capacity by 2030, for the transition away from fossil fields to be on track for net-zero emissions by 2050. This Very Short Introduction describes the main sources of renewable energy--solar PV, wind, hydropower, and biomass--their innovative technologies, and what each could deliver. It also discusses the relatively small contributions expected from tidal, wave, geothermal, and nuclear power, and from carbon capture and storage. Electrification of buildings, industry, and transport for net-zero will roughly triple the supply of electricity, and this can be met predominantly by solar PV and wind power. The learning effect has resulted in a dramatic drop in the price of wind and solar PV power in the last decade, making them the cheapest generators of electricity in most parts of the world. The Very Short Introduction ends by discussing the actions needed that include strong consistent policies, financial initiatives to take advantage of the long-term benefits of renewables, and good community involvement.

Author Information

Nick Jelley is an emeritus professor in the Department of Physics and a fellow of Lincoln College at the University of Oxford. His research was in nuclear and particle physics, and he published many papers in this field. He was a member of the Nobel Prize-winning SNO experiment, for which he was the UK group leader, and the recipient of two Institute of Physics prizes. More recently, he has carried out research on solar energy for use in the developing world. He gave lectures to Oxford physics undergraduates on Energy Studies from 2003-2014, and in 2012 a Science and Society public lecture on renewable energy at the University of Liverpool. His books include Energy Science and A Dictionary of Energy Science. George Reid is an actor and voice-over artist from the UK. Having worked in the industry for over a decade, George has voiced video game characters for Game of Thrones and has worked with Spotify and Ocado, among other brands. He works from his professional, broadcast quality home studio in the UK with some of the industry's highest quality equipment to ensure each audiobook sounds as polished and immersive as possible.
