Top 3 sustainable energy choices
Updated: Jul 13
Wind power transfers kinetic energy to electric using wind turbines.
This is an unpredictable energy source but in the end it is also a clean and green one.
Around 80 countries use this form of energy however in 2010 wind power created 2.5% -which does show that it isn’t hugely effective but it is a very green source of energy.
Tidal power converts underwater ocean currents into useful energy using water turbines and a generator.
It is similar to wind power, but it is less easily seen as it is under water.
The tides are also more predictable than wind and sun alternative.
Tidal power is much more efficient than wind power because water is 1000 times denser than air and therefore creates more energy when the turbines turn.
Hydroelectric power harnesses water in a river or going down a waterfall.
When the water goes down the hill there is a water turbine and this turns as the water goes past.
Similar to wind power this goes to a generator which turns the kinetic energy into electrical.
As time goes on these sustainable alternatives will be used instead of coal and oil, but until then if you continue to educate yourself, when they do become more frequently used you will know exactly which ones are the best for our planet.
Until next time, remember to be your own superhero.
