Renewable energy is a energy from renewable sources that are naturally replenished on a human time scale. Renewable sources include solar, wind biomass, hydro and geothermal.Renewanle energy is often used for electricity generation, heating, and cooling.Renewable energy sources are environmental friendly and doesn't produce any green house gasses into the environment.Renewable energy projectRenewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. From 2011 to 2021, renewable energy grew from 20% to 28% of global electricity supply. Use of fossil energy shrank from 68% to 62%, and nuclear from 12% to 10%. The share of hydropower decreased from 16% to 15% while power from sun and wind increased from 2% to 10%. Biomass and geothermal energy grew from 2% to 3%. There are 3,146 gigawatts installed in 135 countries, while 156 countries have laws regulating the renewable energy sector.In 2021, China accounted for almost half of the global increase in renewable electricity. Globally there are over 10 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer.Renewable energy systems are rapidly becoming more efficient and cheaper and their share of total energy consumption is increasing,[14] with a large majority of worldwide newly installed electricity capacity being renewable.In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity. Many nations around the world already have renewable energy contributing more than 20% of their total energy supply, with some generating over half their electricity from renewables.A few countries generate all their electricity using renewable energy.National renewable energy markets are projected to continue to grow strongly in the 2020s and beyond.According to the IEA, to achieve net zero emissions by 2050, 90% of global electricity generation will need to be produced from renewable sources.Some studies have shown that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable. Renewable energy resources exist over wide geographical areas, in contrast to fossil fuels, which are concentrated in a limited number of countries. Deployment of renewable energy and energy efficiency technologies is resulting in significant energy security, climate change mitigation, and economic benefits. However renewables are being hindered by hundreds of billions of dollars of fossil fuel subsidies. In international public opinion surveys there is strong support for renewables such as solar power and wind power.In 2022 the International Energy Agency asked countries to solve policy, regulatory, permitting and financing obstacles to adding more renewables, to have a better chance of reaching net zero carbon emissions by 2050

17. Top 5 solar Panel manufacturing in India
India, with its abundant sunlight, has recognized the importance of solar
energy in its energy mix. As a country striving for sustainable development,
India has set ambitious goals to increase its share of renewable energy.Solar
power plays a crucial role in achieving these targets, as it is a clean and
inexhaustible source of energy.
