Historically, most countries have relied on fossil fuels like coal, petroleum, and natural gas for energy production. However, fossil fuels release carbon dioxide and other greenhouse gases, causing air pollution and climate change from heat trapped in the atmosphere.
The proven link between fossil fuel usage and climate change has spurred many countries to invest heavily in and create favorable policies for non-polluting, renewable energy. 195 countries, or all United Nations-recognized sovereign states, have signed the Paris Agreement, a legally binding treaty to reduce greenhouse gas emissions and curb global warming.
Transitioning to a carbon-free, renewable energy-based world requires massive investments and policy shifts. Despite exponential growth in the renewable energy sector, coal, oil, and gas currently constitute 81% of global energy consumption.
Decarbonizing the global energy industry is feasible…
