 Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services. Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. Both, modern renewables, such as hydro, wind, solar and biofuels, as well as traditional biomass, contributed in about equal parts to the global energy supply. Worldwide investments in renewable technologies amounted to more than US$ 214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels. Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits. In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. United Nations' Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity. A mandatory renewable energy target is a government legislated requirement on electricity retailers to source specific proportions of total electricity sales from renewable energy sources according to a fixed timeframe. The additional cost is distributed across most customers by increases in other tariffs. The cost of this measure is therefore not funded by government budgets, except for costs of establishing and monitoring the scheme and any audit and enforcement actions. At least 66 countries, including 27 EU countries have renewable energy policy targets of some type. The EU baseline target is 20% by 2020. While the USA does not have a national RET, 29 of its states do. Similarly Canada has 9 state RETs but no national target. Targets are typically for shares of electricity production, but some are defined as by primary energy supply, installed capacity or otherwise. While some targets are based on 2010-12, many are now for 2020 which ties in with the IPCC suggested greenhouse gas emission cuts of 25 to 40% by Annex I countries by 2020, although some are for 2025.

Jeremy Leggett, a geologist by training, began his career as a consultant for the oil industry, while teaching at the Royal School of Mines. He later became an environmental campaigner for Greenpeace, before evolving into a social entrepreneur and author. Jeremy Leggett is currently executive chairman of Solarcentury the UK’s largest independent solar electric company. He also serves as a founding director of the world's first private equity fund for renewable energy. From 2002 to 2006, Leggett was a member of the UK Government Renewables advisory board. He was the recipient of the President's Award of the Geological Society, and in 1987 the Geological Society's Lyell Fund. In his 2009 book, The Solar Century, Leggett is critical of nuclear power, saying that investing in nuclear power would mean less money for other initiatives involving energy conservation, energy efficiency, and renewable energy. Leggett also states that carbon capture and storage has a "substantial timing problem" as it will take fifteen to twenty years to introduce the technology.

This needs to happen in the industrialized world, as well as in the emerging markets of the developing world where most future GHG emissions will occur.
