Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns. Solar photovoltaics are the fastest growing electricity source.The amount of electricity generated by wind increased by 265 TWh in 2022 (up 14%), the second largest growth of all power generation technologies. Wind remains the leading non-hydro renewable technology, generating over 2 100 TWh in 2022, more than all the others combined.Wind energy Energy generated from the kinetic energy of moving air. Wind energy is the fastest growing major source of electricity in the world. Solar power is one of the cleanest forms of energy because it does not emit any greenhouse gases. It also produces no harmful by-products.Solar Power: 67.07 GW. Biomass/Co-generation: 10.2 GW. Small Hydro Power: 4.94 GW. Waste To Energy: 0.55 GW. Wind power has been the fastest growing energy source in the world since it became more cost-effective in the 1990s, though it has a long way to go to catch up with hydro power. It is generally believed that wind is the most efficient way to harness renewable energy. Because windmills can be placed in open areas also used for farming, they offer flexibility. Generally, rows of wind turbines are constructed along coastal areas where nothing can hinder the flow of wind.Global solar PV capacity is set to almost triple over the 2022-2027 period, surpassing coal and becoming the largest source of power capacity in the world. Hydrogen has the best chance of being widely used in the future. Sources of hydrogen are plentiful, it has many uses, and most of the needed technology has already been developed. Hydropower is the most widely-used renewable power source, with the global hydroelectric installed capacity exceeding 1,295GW, accounting for more than 18% of the world's total installed power generation capacity and more than 54% of the global renewable power generation capacity.Globally we get the largest amount of our energy from oil, followed by coal, gas, and then hydroelectric power. As we look at in more detail below “How much of global energy comes from low-carbon sources?” the global energy mix is still dominated by fossil fuels. They account for more than 80% of energy consumption. In the industrial sector, biomass makes up 98 percent of the renewable energy use with roughly 60 percent derived from biomass wood, 31 percent from biofuels, and nearly 7 percent from biomass waste.
