Soooo then in 40 years what will replace Nuclear? LNC? Because it seems Renewables are a long way from being able to carry a base load and even if they could, the land and resources required is staggering.
Human resourcefulness and innovation is unlimited, and can't be predicted. Rest assured, humans will be inventing what we need for the future.
We have roadblocks to human innovation, well funded and well connected lobbyists, propagandists, and saboteurs for the fossil fuel industry, squashing renewable energy as much as they can.
If we continue and increase our efforts to squash the fossil fuel industry instead, entrepreneurs, innovators, inventors
and investors will quickly find ways to promote and profit from renewables.
What's that principle? ... 'An object in motion will remain on it's course until acted upon by another force.'
We have to apply 'the force' to change the direction, and human ingenuity will provide the methods.
