Simple solutions for the climate crisis, which should have been implemented already
We already know what to do to solve climate change:
- use less energy
- increase energy generation from sustainable sources
- phase out energy generation from fossil fuel sources
- reduce methane release
Some politicians talk as if we need new technological solutions to the climate crisis, but we don't: we just need existing technology to be implemented.
Use less energyThe enormous amounts of energy that are used in some developed countries are not essential for a healthy prosperous society.
Increase energy generation from sustainable sourcesIn the past, all energy used came from sustainable sources: burning sustainable fuels, windpower and waterpower. The industrial revolution was based on the use of charcoal (to make iron) and water power (to power factories) - these are both sustainable fuels.
Reduce CO2 and methane emissionsOf the greenhouse gases, it is the CO2 emissions that must be reduced the most - firstly because CO2 has the largest effect, and secondly because it persists in the atmosphere for centuries and possibly millenia. Methane in the atmosphere has a lifetime of around 12 years .
