For the first time ever, solar is set to generate more electricity than coal in the power market managed by the Electric Reliability Council of Texas. Nobody is building new coal power plants in the state, but developers are adding more solar there than anywhere else in the country. As a result of those diverging trajectories, the federal government expects ERCOT will receive 78 billion kilowatt-hours from solar in 2026, and just 60 from coal.
This trend does have seasonal variations. Last year, solar output beat coal on a monthly basis from March through August, and this year it is expected to do so from March through December, per the US Energy Information Administration at the Department of Energy.
Did you know that during the 18th and 19th century industrial revolution in Britain, coal never became cheaper than water power? All those new steam engines were used to make deeper mines more viable and to increase production. But water power remained cheaper throughout. But water power came with a downside. Available water power tended to be located in rural areas. The smaller population in these small towns consequently had a lot of labor bargaining power. Industrialists instead wanted access to the labor markets of the major cities, cities brimming over with new urban poor desperate for any scrap of work they could get. Cheaper labor overcame cheaper power. A coal plant could be put anywhere, while a water mill could only be positioned on high-flowing streams.
Renewables are cheaper, but we’ve been here before. There’s more to this than just energy cost.
Do you have any source for that? I find it difficult to believe that the only reason for using steam over water mills was the dastardly exploitation by capitalists.
