Is renewable energy actually renewable?
Renewable energy includes resources that rely on fuel sources that restore themselves over short periods of time and do not diminish. Such fuel sources include the sun, wind, moving water, organic plant and waste material (eligible biomass), and the earth’s heat (geothermal).
Can we go 100% renewable?
100% renewable energy and net-zero greenhouse gas definitions are political in nature and vary by place and time. However, recent studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and desalination well before 2050 is feasible.
