Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, rain, tides, waves, and geothermal heat.
These sources are naturally replenishing but flow-limited. They are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time.
In 2020, almost 5% of the energy consumed across sectors in the US was from renewable sources.
And while renewable energy sounds great and amazing in theory, there are challenges.
What is the big problem with renewable energy? Are electric cars, solar panels, wind turbines conserving the earth's resources and putting an end to pollution?
Quite the contrary; these technologies rely on rare minerals and add pressure on their resources. Mining for them releases radioactive substances & refining them needs thousands of gallons of water.
