And yet, compared to energy generated through fossil fuels, it’s still peanuts.
Only because our society relies way too much on fossil fuels so the numbers are astronomical, and unsustainable
The key point here is the change for sustainable energy started years ago despite some people claiming it´s not possible. We can discuss if it´s possible or not, but the fact is it started years ago
Not saying it´s real today or it will be next year, but we´re talking about a HUGE change wich affects the whole planet and society, so we can´t expect it will happen in 5-10 years, a change of this scale will always take much longer obviously
But like it or not, believe it or not, hate it or not, it´s already happening. Thankfully!!
Fully agree. Unfortunately, exponential growth is hard to grasp for people (see Covid, too). But things are well on their way, and that without fair pricing, mind you. While some people complain renewables are not viable without subsidy, there are still various tax breaks and other forms of implicit subsidy for fossil fuels. Still, some forms of renewable energy are already competitive, subsidy-free. And that's not even going into inclusion of external (health- and climate-change) related costs in the fossil fuel price yet - if we would start doing so, it's really over and out for fossils.
Jevon's paradox suggests otherwise, as does the projection that the Saudis can pump oil at $10 a barrel and still come out with a profit. If nothing else, developing countries seem to have two options:-
1) Continue with their current energy trajectory, with it being even cheaper as the pressure of renewables forces fossil fuel prices down.
2) Completely revamp their infrastructure, writing off most of the money invested so far, to shift to a low carbon model.
The first of those options seems pretty attractive. If that's the case, then there needs to be incentives to make the second option the better option. Those incentives will likely have to come from developed nations which will effectively drive up the price of renewables. Hydrogen rather than solar/wind/water might get around that, as it's more efficient to transport although there are big issues around energy security and the current drive seems to be towards solar/wind/water.
It really feels like we missed the boat back in the '70s.
