In 2019, the world’s total energy supply was 606EJ, wherein the highest share in terms of source was captured by oil, accounting for 30.9%, followed by coal (26.8%), natural gas (23.2%), biofuels and waste (9.4%), nuclear (5.0%), hydro (2.5%), and other (2.2%). Where there was an increase in energy demand in 2018, the year 2019 witnessed slow growth as the energy efficiency improved owing to decline in the demand for cooling and heating. However, in 2020, the electricity demand decreased by 1% due to the outbreak of Coronavirus resulting in government imposed shutdowns in order to limit the spread of the virus, which was further followed by shutdown of numerous business operations impacting their growth. This also resulted in decline of 5.8% in the worldwide CO2 emissions which was recorded to be five times larger than the one recorded during the global financial crisis in 2009. However, in 2021, the demand for oil, gas and coal is estimated to witness growth, which is further projected to create opportunities for market growth. Moreover, rising environment degradation and awareness related to climate change is motivating many key players to employ sustainable energy strategies and invest significantly in environment-friendly power generation technologies with an aim to promote sustainable development among various nations around the world. Such factors are anticipated to promote the growth of the market in upcoming years.
