In the future we are not sure what resources we will use to provide energy across the globe. This a global problem becuase we need energy in order to do everything we do like communicate, learn, and many other things.
The Solution: use more long lasting energy sources such as wind and hudro power.
Pros: Hydroelectric energy is renewable and flexible, Wind is renewable, freely available and tax-free.
cons: Equipment requires a sizeable upfront investment, and In time of drought, hydroelectric power plants aren't able to produce electricity because there isn't enough water.
some new technologies for these solutions are wind turbines and hydro electric generators. A major company making advances towrards these energy resources is NASA
