With available tech, solar power alone could provide almost 4 X the world's current energy
Using already-available technology, solar power alone could provide almost four times the world's current energy use; wind or geo-thermal power each could exceed todays energy use. Yet, 80 percent of our energy still comes from burning fossil fuels that increase C02 concentrations ” triggering climate chaos, disrupting nature, and further concentrating wealth. The convenient truth is that we can choose instead abundant, renewable energies that can meet our needs, more safely, and help to decentralize power.
