The Future of Power: Energy Sources We’ve Got to Look Forward To

Geothermal Energy

As appealing as fusion and wind are, though, there’s certainly something to be said for an energy source that doesn’t depend on expensive reactor facilities or unreliable weather conditions. Enter geothermal energy: heat pulled straight from beneath the surface of the Earth, where there’s always plenty. Now technically, we’ve been harnessing geothermal energy for over a century by just collecting it from water and steam. But modern geothermal harnessing techniques are limited, both in range of use (even when the technology is mature, it’s mainly used for basic heating and cooling functions) and by geography itself (we have to harness the heat where it is, almost always in tectonically active areas).

However, we’re constantly improving at both getting to the heat and spending less money, effort and time doing it. And in the very near future, expect technologies falling under the umbrella of Enhanced Geothermal Systems, which drill and pour water into ‘hot dry rock’ areas in the earth’s crust in order to turn the currently inaccessible energy stores there into several times more usable, clean energy than fossil fuels currently give us access to, to reshape the energy landscape.
