Question

I am collecting information about renewable energy

Answer 1

Explanation:

Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.[3] Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.[4]

Based on REN21's 2017 report, renewables contributed 19.3% to humans' global energy consumption and 24.5% to their generation of electricity in 2015 and 2016, respectively. This energy consumption is divided as 8.9% coming from traditional biomass, 4.2% as heat energy (modern biomass, geothermal and solar heat), 3.9% from hydroelectricity and the remaining 2.2% is electricity from wind, solar, geothermal, and other forms of biomass. Worldwide investments in renewable technologies amounted to more than US$286 billion in 2015.[5] In 2017, worldwide investments in renewable energy amounted to US$279.8 billion with China accounting for US$126.6 billion or 45% of the global investments, the United States for US$40.5 billion and Europe for US$40.9 billion.[6] Globally there are an estimated 7.7 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer.[7] Renewable energy systems are rapidly becoming more efficient and cheaper and their share of total energy consumption is increasing.[8] As of 2019, more than two-thirds of worldwide newly installed electricity capacity was renewable.[9] Growth in consumption of coal and oil could end by 2020 due to increased uptake of renewables and natural gas.[10][11]

Answer 2

Answer:

Renewable resources are those which can be replenished once they are exhausted completely. Eg. water which is replenished by the process of water cycle.
