Can 100% renewable energy power the world? - Coggle Diagram
Can 100% renewable energy power the world?
present
-The world consumes 35B barrels of oil per year.
-40% of the world's oil has already been consumed
-We will run out of oil and gas in 50 years and in 100 years without coal.
renewable energy
-We have renewable energy, sun, water and wind.
-renewable energies only cover 13% of what we need.
-electricity and liquid fuel.
solar panels:
-technology already allows the use of the sun's rays as energy through solar panels
-these produce 173 quadrillion watts of energy on earth.
-Only with hundreds of thousands of km of panels it was possible to produce the energy that society currently needs.
-The panels must be in deserts and places with a lot of sun, but they are far from society.
other forms
-Ways to produce energy, hydroelectric, geothermal and biomass.
-availability and location problems.
energy transport
-The infrastructure to transport energy should change, but it is very expensive.
-The current power lines lose 6 to 8% of energy that is transported.
-superconductors could be a solution, but there are too many complications.
-An efficient way to transform renewable energy would be to convert solar energy into chemical energy, but the efficiency is still low.
solution
-for a true solution we will need creativity, innovation and powerful incentives.
-involves technology, economics and politics.
-There are many reasons to believe that it is possible to use renewable energy forever
-scientists are already working on it
-Governments invest in technology
