I think we've seen too much of a mixing of politics and science over the last few decades. There are scientists who claim that solar and wind power will save the world. In reality, due to the need for spinning reserve, all of the solar and wind installations to date have had minimal impact on carbon emissions. Spinning reserve is power that a power company must have available on short notice. Some laws say the spinning reserve must be available in ten minutes, but most companies want it available immediately to prevent brownouts and blackouts.
Conventional power plants, be they coal fired, gas fired, oil fired, or nuclear, generate power the same way. They heat massive quantities of water in a pressure vessel to convert it to steam that then drives a turbine that then spins a generator creating power. Since a conventional power plant must be used for spinning reserve those plants must be kept up and running, just as if they were generating the power. You can't get a cold plant up and generating power in a short period of time, so the plants are kept up and running, burning the fuel of whatever type to heat the water so when a cloud passes over the solar panels or the wind stops blowing, the power stays on. The best analogy is it's like you buy an electric powered car to save the planet, but then because you don't trust the reliability of the electric car, you have someone follow you everywhere in a gas powered car. The net gain is nothing.
Now there's talk of building massive lithium ion battery warehouses to serve as spinning reserve and companies like Tesla are making home batteries (their Powerwall) to try and help with these issues, but to date, all of the billions that have been spent on solar and wind installations have achieved little or nothing due to spinning reserve. All the power that they're generating is being backed up by conventional power plants churning away in the background, burning the fuel just as though they were actually generating the power in case they're needed. You just can't turn massive quantities of water to steam instantly, so the plants have to be kept up and running to be ready when needed.
Conventional power plants typically have the spinning reserve built capabilities built into the plant in the form of additional turbines or generators that can be activated as needed, so there's no offset provided by the solar or wind power. The reality is that given the need for spinning reserve, solar and wind power are nothing more than a placebo. They look impressive, politicians and scientists can say, "Look we're doing something!" But they're achieving nothing, other than wasting billions of dollars.
At this moment the only real answer to reducing carbon emissions is nuclear power. If you don't mind some carbon emissions then small, natural gas powered generators forming mini-grids in neighborhoods might be a good long term solution. The reality is that everyone, scientists, politicians, and lay people fall in love with a concept and assume it to be true. Solar and wind power as the savior of the world is a concept that many have fallen in love with. A closer look reveals that's not true due to spinning reserve.
Oddly enough, the old passive solar systems in wider use in the seventies/eighties to help heat homes do more good to reduce carbon emissions than the photovoltaic panels that are the current trend. The heat captured in a passive solar system directly offsets the fuel that would be needed to burn to generate that heat. There is no spinning reserve needed for a home heating system. If the sun isn't shining your home heater works as normal. If the sun is shining the heat from the passive solar design is free and the heater isn't needed saving the fuel and carbon emissions that would be created. When was the last time you saw a scientist or politician actively pushing for more use of passive solar designs in new home construction? Homes designed to take advantage of passive solar gain would be many times more effective in reducing carbon emissions than photovoltaic or wind power. Unfortunately there's not a big passive solar energy industry out there making billions of dollars, so that's largely ignored these days.
If scientists want politicians to take them seriously, then they have to be open to re-examining their own beliefs and views. Screaming politicians don't care about the environment because they won't spend more money to build more solar and wind installations when solar and wind installations achieve nothing, doesn't help the cause. Push for nuclear power, cleaner burning natural gas, more use of passive solar, or other truly effective solutions, and politicians might just listen more. It would take a very bold scientific community to rise up and tell the world that solar (photovoltaic) and wind power have been a waste of money and that we should look for other options. Such boldness might just impress the politicians however.
