Energy
This page is about energy in 2 main forms: fuel and electricity.
Energy supply
The majority of energy comes from fossil fuels which cause climate change.
Limits to other energy sources
| Energy source | Limitations |
|---|---|
| Hydroelectricity | Only viable in a few parts of the world |
| Geothermal | In most parts of the world, is only suited for heating and cooling |
| Solar | 1. Intermittant (not available at night) 2. Manufacturing is too resource-intensive |
| Wind | 1. Intermittant 2. Turbine construction is too resource-intensive 3. Requires a lot of space, usually far from where people live |
| Nuclear | Limited supply of uranium-235 + Safety concerns |
| Biomass waste | Limited supply |
| Biofuel | Limited supply + Competes with food, contributing to hunger and deforestation |
The intermittency problem of solar and wind could be solved with energy storage, if the right innovations happen.
