In 2015, it only accounted for 1.05% of electricity generation, but at current rates of growth, solar will dominate the energy market in the next 10-20 years.
CO2 emissions will decline. The coal and oil industries are doomed. The solar revolution is coming sooner than people think.
* Just kidding *
I'll grant that things can always get worse, but it's already affecting our generation significantly.
The main problem with solar energy in frequency stability on those regions, a problem of its own
It's much easier and safer to work with a broad spectrum of renewable energy as there the risks of failure have fewer consequences.
People die falling off of roofs installing solar panels, get chewed up by wind turbines, fall into dams, etc. all for nearly insignificant percentages of what a single nuclear plant can come up with. Coal and other fossil fuels of course are orders of magnitude more harmful.
It's currently at 2.3%, and growing at a slower rate of 15% per year. At this rate in 2060~ it will account for 221% of energy production in the world
That is why while solar power was increasing of 50% its share in total energy consumption didn't increase that much. Personnally I think photovoltaics aren't the way to go about solar energy, it is wasteful and inefficient. Solar energy should be used mostly to warm up houses without transforming it into electricity.
If solar makes up 1.05% of the energy supply and grows at 50% per year, that means every year it grows by 50%*.0105E = .525% of E every year.
Coal energy is currently growing faster, in raw numbers.
If the growth in solar energy remains the same relative to its share of the energy market, then it should eventually 'dominate' over coal, but as long as coal and other fossil fuels continue to grow as well it does nothing useful for CO2 reductions. Both are driven by rising energy demand; they don't supplant the other.
The good news is that the growth of fossil fuel energy should slow and then reverse as solar energy becomes the cheaper alternative, and it is price reductions for solar, not its growth rate, that mean solar will, hopefully, dominate in the next 10-20 years.
The writing is on the wall for fossil fuels - adapt or perish.
However, China is mostly building supercritical and ultrasupercritical coal power plants. These plants are far more efficient than the smog producing monsters that you generally think about. About 22% more energy per ton of coal burned but also a fraction of the nitrous, sulfur, or particulate emissions of subcritical plants. They also tightened their emissions standards. It will take a long time to replace their existing dirty fleet of coal plants, but that is generally what they're doing.
So while they're building new coal plants, they CAN be cleaning up their emissions. Similar to how we have cleaned up ours by replacing coal with natural gas.
If you could tick off at least 4 things on the list chances are the country is on the quiz.
not socially acceptable in a densely populated island to have vast open cast mining, thank goodness.
Australia's governments, and in fact, it's quality of life is subsidized by environmentally harmful activities. Iron ore is another huge industry.
All told, coal and iron ore represented more than 50% of Australia's exports in 2022.
Most of the coal is, of course, shipped off to Asian countries like Japan. It's not the worst thing ever, since Australian coal tends to be cleaner and have higher energy density than other grades. Still, it's not ideal. In my opinion, Australia is up there with Saudi Arabia and Canada as possibly the worst country for the environment on a per-capita basis.
Brazil is probably already the 5th largest solar energy producer on the world, if not it will be in matter of months. (Not sure how australia is going right now).
Brazils largest energy production still comes from waterplants, but solar plants are already 2nd place and windplants 3rd place, making it about 81% of its power capacity renewable.
LGN is about 9%, and Oil+Diesel+Coal less than 4%.
