Can it really replace fossil fuel fired powerplants? Are there any countries that derive the majority of their electricity from solar and wind?

The Earth received more than 8,000 times as much energy from the sun as humans use in all forms so it's robust enough of a power source to do the job. The issue is largely with power storage and transfer since the sun only illuminates half the Earth at any given time.

The UK gets roughly 50% of its power from renewables on windy days.

The key is better storage and less irrational nonsense about nuclear.

And collection space efficiency.

You only get 200 watts per square meter with current pv panels. Unless you want to blanket wilderness in black glass.

It makes me wonder if the future of power is a smart grid with decentralized power generation. For example, having solar panels on the roof of a hundred thousand houses instead a few big solar fields.

Funny, read something like that earlier.

https://oilprice.com/Alternative-Energy/Renewable-Energy/Microgrids-Are-The-Future-Of-Energy.html

Any well off home and plenty of businesses with big roofs will be pretty much energy independent going forward with some grid usage in winter and in case of battery failure. Solar plants might create methane/hydrogen for winter peaking plants to cover the sunlight gap.

Space isn't an issue. The efficiency of solar is roughly 20%. 20% of 8,000 is 1,600 and if we only collect 60% of that sunlight due to lack of tracking we're left with 960 times the energy we need which means we need to cover 0.1% of the Earth with solar panels to cover what we use currently. Also wind is more power dense for the same footprint so this figure can be reduced with greater adoption of wind power.

That's the direction I see it going, especially if electric vehicles gain more traction. The batteries can be used to store energy when it's cheap and sell it back to the grid when it becomes more expensive. An HVDC supergrid could allow states on the east coast to sell solar power to the west coast and vice versa which would effectively extend the time solar produces power.

To power NYC for a day. You need 11 kurnool solar power parks and hundreds of hornsdale power reserves. At bare minimum 70,000 acres of land. 1/13th the area of long Island.

On a good sunny day that isn't too hot.

Looks like it's completely safe outside the plant and maybe one old employee might have a condition worsen while there and die, other than that it provided decades of clean energy

Quoted By:

>>12088792
Some nations are 100% renewable for years. But mainly because of hydro power.
Some nations got a high share of wind
Denmark 41.8%
Lithuania 26.9%
Germany 24.7%
Portugal 20.7%
Ireland 20.2%
Spain 17.8%
UK 17.1%

meanwhile solar is growing fast
Germany 9.0%
Italy 7.6%
Greece 7.2%
Spain 5.0%
UK 3.9%

This year will break records because demand was lower. e.g. UK had shut down all coal plants for months. This is first time it happened since the industrial revolution. Meanwhile wind and solar are cheaper so only this is being build.

In my understanding, these had a fatal problem of being eroded by salty sea wind hitting the blades at a high speed. Significantly reduced lifetime.

not fatal in the least, there are still massive extremely successful offshore wind projects. They're just more expensive than land based wind.

There are tests to build continuous hydrothermal liquefaction plants that convert most biomass into biocrude, nutrient-rich water and compost sludge using supercritical water
Since most of the energy needed is heat, you could put solar concentrators on the roof of a plant to power the process and use the city’s waste biomass to make crude oil and Biogas from a biodigester
So you could make hydrocarbons and recycle waste biomass using CSP and a giant thermos heat battery

The problem with biomass is that it only stores about 10% of the sun's energy and you only get about a third of that back when you burn it so it would be more efficient to install solar panels rather than grow biomass to burn. Might be a cool way to deal with waste though.

That doesn't sound all that promising when you think about how much of the surface of the Earth is oceans and areas we'd rather leave wild instead of covering with solar panels.

Measuring additions to grid by capacity is rather pointless when you look at the different capacity factor of each source. Which means if you add a gigawatt capacity solar plant only about 160 megawatts will actually go into the grid
Wind with around 30% and solar around 16% compared to coal and gas with 50% and nuclear with 90%
