Understanding Green Energy
Green energy refers to any renewable source that has minimal environmental impact such as solar, wind, hydroelectricity, geothermal heat, or biomass power production. As opposed to fossil fuels which contribute significantly to pollution and climate change, these forms of green energy generation tend to be renewable and cleaner alternatives than their fossil counterparts.
· The Importance of Green Energy
Green Energy Its Transitioning to green energy is necessary for several reasons. First, it addresses the urgent need to curb greenhouse gas emissions that contribute directly to climate change; second, it enhances energy security by decreasing dependence on imported fossil fuels; third it boosts economic development through green job creation and development of innovative industries.
· Historical Context
Since 1870, humanity has relied heavily on fossil fuels for energy. Coal, oil, and natural gas have powered economies around the globe for well over 100 years – but their environmental and health costs are becoming ever more apparent; witnessed most notably through the oil crises of the 70s, the Chernobyl disaster, climate catastrophes as well as more recently climate catastrophes that demonstrate this need to transition away from this path towards cleaner forms of power generation.
