Energy and powered devices are an integral part of

society. Humanity's earliest days saw the discovery of

fire through wood combustion, and the use of charcoal

for smelting metals dates back as early as 5000 BC.

Powered devices using natural energy sources such

as water and wind were introduced by the Ancient Greeks and were commonly used until the 18th century steam engine revolutionized the way devices could be powered. Various natural oils were used for a range of purposes, such as whale oil for lamps. The Industrial Revolution led to the massive use of coal as fuel, and the extraction of petroleum and various other oils became extremely important with the advent of internal combustion engines. Electrical power, also based on fossil fuels, became widespread at the end of the 19th century and the production of cleaner electrical

Since the Industrial Revolution, the energy mix of most countries across the world has become dominated by fossil fuels. This has major implications for the global climate, as well as for human health. Three-quarters of global greenhouse gas emissions result from the burning of fossil fuels for energy. And fossil fuels are responsible for large amounts of local air pollution – a health problem that leads to at least 5 million premature deaths each year.

To reduce CO2 emissions and local air pollution, the world needs to rapidly shift towards low-carbon sources of energy – nuclear and renewable technologies.

Renewable energy will play a key role in the decarbonization of our energy systems in the coming decades. But how rapidly is our production of renewable energy changing? What technologies look most promising in transforming our energy mix?
