The use of renewable energy technologies minimizes air pollution and produces no greenhouse gases. Solar energy, biomass energy, tidal energy, and wind energy are among the extensively widely used renewable energy technologies.
FREMONT, CA: Since a number of the world's largest economies are looking to reduce their reliance on high-polluting fossil fuels, clean energy has experienced massive growth in popularity. Around the world, six different types of renewable energy are used, including wind and solar energy.
As many of the largest economies look to reduce their dependence on high-polluting fossil fuels amid the energy transition, clean energy has experienced a massive rise in popularity.

Globally, 28 percent of electricity was generated from renewable sources in 2018, and 96 percent from hydropower, wind, and solar. In its International Energy Outlook 2019, the US Energy Information Administration (EIA) predicted that renewable energy will account for 49 percent of global electricity generation by 2050.
NS Energy profiles different types of renewable energy technologies that are listed below:
Solar energy: As one of the cleanest and most abundant sources of renewable energy, solar energy converts solar energy into thermal or electrical energy.
As solar photovoltaic (PV) grows in scale, its costs are decreasing since it is the most established low-carbon energy source.
An average of 125GW of new solar capacity is expected globally between 2021 and 2025, according to the International Energy Agency (IEA).
Wind energy: Several countries have turned to wind energy to reduce their emissions, making it one of the fastest-growing renewable energy sources.
Using the kinetic energy generated by air in motion, the wind is used to produce electricity. Wind turbines or wind energy conversion systems convert wind energy into electricity.
Onshore, where the technology is most widely used - or offshore, using fixed-bottom turbines anchored to the sea floor or, on a smaller scale, floating structures.
Energy from biomass: The term biomass refers to all plant and animal material, including wood, animals, and agricultural waste. Typically, it is used as wood pellets in power generation.
Eventually, when coal-fired power plants are being phased out due to environmental and climate concerns, it is becoming increasingly popular as an alternative.
In comparison to finite fossil fuels, biomass sources such as plants, manure, and waste are considered renewable energy sources.
Tidal energy: As opposed to wind and solar energy, tidal energy is generated by converting energy from tides into power.
Even though tidal power became operational in 1966, it is still not widely used.
The increasing global focus on generating electricity from renewable sources will, however, accelerate the development of new ways to exploit tidal energy.
