Renewable energy is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can move heat and vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power.
REN21 is a policy network and a multistakeholder governance group which is focused on renewable energy policy.
For solar power, South Asia has the ideal combination of both high solar insolation and a high density of potential customers.
The Global Wind Energy Council (GWEC) was established in 2005 to provide a credible and representative forum for the entire wind energy sector at an international level. GWEC’s mission is to ensure that wind power is established as one of the world’s leading energy sources, providing substantial environmental and economic benefits.
International Renewable Energy Alliance is a formal partnership entered into on 4 June 2004 by five non-profit international renewable energy organisations:
Renewable Energy in Colombia is rapidly emerging as a pioneer in the clean energy transition, showcasing a commitment to climate action despite its status as a fossil fuel-producing nation. With a robust National Energy Plan extending to 2050, the country has set ambitious targets for diversifying its energy mix by incorporating wind, solar, and geothermal resources. The nation's resolve was further solidified at COP26 with the announcement of a net zero target and a Nationally Determined Contribution (NDC) aiming for a 51% reduction in greenhouse gas emissions by 2030. Significant investments in renewable energy infrastructure, particularly through long-term auctions for large-scale solar and wind projects, are transforming Colombia's energy landscape.

Preben Maegaard was co-founder of the Nordic Folkecenter for Renewable Energy, established in 1983, and its director 1984 till 2013 (www.folkecenter.net).
Renewable energy in Canada represented 17.3% of the Total Energy Supply (TES) in 2020, following natural gas at 39.1% and oil at 32.7% of the TES.
The International Hydropower Association (IHA) is an international lobby group and membership association representing the global hydropower sector.
Renewable energy in Russia mainly consists of hydroelectric energy. Russia is rich not only in oil, gas and coal, but also in wind, hydro, geothermal, biomass and solar energy – the resources of renewable energy. Practically all regions have at least one or two forms of renewable energy that are commercially exploitable, while some regions are rich in all forms of renewable energy resources. However, fossil fuels dominate Russia’s current energy mix, while its abundant and diverse renewable energy resources play little role.
Most of Kenya's electricity is generated by renewable energy sources. Access to reliable, affordable, and sustainable energy is one of the 17 main goals of the United Nations’ Sustainable Development Goals. Development of the energy sector is also critical to help Kenya achieve the goals in Kenya Vision 2030 to become a newly industrializing, middle-income country. With an installed power capacity of 2,819 MW, Kenya currently generates 826 MW hydroelectric power, 828 geothermal power, 749 MW thermal power, 331 MW wind power, and the rest from solar and biomass sources. Kenya is the largest geothermal energy producer in Africa and also has the largest wind farm on the continent. In March 2011, Kenya opened Africa's first carbon exchange to promote investments in renewable energy projects. Kenya has also been selected as a pilot country under the Scaling-Up Renewable Energy Programmes in Low Income Countries Programme to increase deployment of renewable energy solutions in low-income countries. Despite significant strides in renewable energy development, about a quarter of the Kenyan population still lacks access to electricity, necessitating policy changes to diversify the energy generation mix and promote public-private partnerships for financing renewable energy projects.
Ethiopia generates most of its electricity from renewable energy, mainly hydropower.
Renewable energy in Mexico contributes to 26 percent of electricity generation in Mexico. As of 2009, electricity generation from renewable energy comes from biomass, hydro power, geothermal, solar power and wind. There is a long term effort established to increase the use of renewable energy sources. The amount of geothermal energy used and harvested, places Mexico as number four in the world.
Renewable energy in Bhutan is the use of renewable energy for electricity generation in Bhutan. The renewable energy sources include hydropower.
The International Renewable Energy Agency (IRENA) is an intergovernmental organization mandated to facilitate cooperation, advance knowledge, and promote the adoption and sustainable use of renewable energy. It is the first international organisation to focus exclusively on renewable energy, addressing needs in both industrialised and developing countries. It was founded in 2009, and its statute entered into force on 8 July 2010. The agency is headquartered in Masdar City, Abu Dhabi. The Director-General of IRENA is Francesco La Camera, a national of Italy. IRENA is an official United Nations observer.
Renewables supply a quarter of energy in Turkey, including heat and electricity. Some houses have rooftop solar water heating, and hot water from underground warms many spas and greenhouses. In parts of the west hot rocks are shallow enough to generate electricity as well as heat. Wind turbines, also mainly near western cities and industry, generate a tenth of Turkey’s electricity. Hydropower, mostly from dams in the east, is the only modern renewable energy which is fully exploited. Hydropower averages about a fifth of the country's electricity, but much less in drought years. Apart from wind and hydro, other renewables; such as geothermal, solar and biogas; together generated almost a tenth of Turkey’s electricity in 2022. Over half the installed capacity for electricity generation is renewables.
In 2013, renewable energy provided 26.44% of the total electricity in the Philippines and 19,903 gigawatt-hours (GWh) of electrical energy out of a total demand of 75,266 gigawatt-hours. The Philippines is a net importer of fossil fuels. For the sake of energy security, there is momentum to develop renewable energy sources. The types available include hydropower, geothermal power, wind power, solar power and biomass power. The government of the Philippines has legislated a number of policies in order to increase the use of renewable energy by the country.
There is enormous potential for renewable energy in Kazakhstan, particularly from wind and small hydropower plants. The Republic of Kazakhstan has the potential to generate 10 times as much power as it currently needs from wind energy alone. But renewable energy accounts for just 0.6 percent of all power installations. Of that, 95 percent comes from small hydropower projects. The main barriers to investment in renewable energy are relatively high financing costs and an absence of uniform feed-in tariffs for electricity from renewable sources. The amount and duration of renewable energy feed-in tariffs are separately evaluated for each project, based on feasibility studies and project-specific generation costs. Power from wind, solar, biomass and water up to 35 MW, plus geothermal sources, are eligible for the tariff and transmission companies are required to purchase the energy of renewable energy producers. An amendment that introduces and clarifies technology-specific tariffs is now being prepared. It is expected to be adopted by Parliament by the end of 2014. In addition, the World Bank's Ease of Doing Business indicator shows the country to be relatively investor-friendly, ranking it in 10th position for investor protection.
Renewable energy in South Africa is energy generated in South Africa from renewable resources, those that naturally replenish themselves—such as sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas: electricity generation, air and water heating/cooling, transportation, and rural energy services. The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy. South Africa's greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.
