From 2004-2015, worldwide solar power production increased at 51% per year!

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.

Solar power is a good supplement, but not primary energy source. It's too costly to store it. Creating the batteries necessary to store large amounts of solar energy becomes inhibitively costly very quickly. Petrol is ready to be converted into energy instantly and at any time of day.

Even as a supplement, solar could drastically reduce our dependency on fossil fuels. It really is foolish not to use it to its fullest capabilities.

No longer true, storage methods have vastly improved. We can now use solar power more smartly to store energy. We can use it to pump water uphill for future use through a hydroelectric dam; we can also store it as heat energy in cheaper substances (such as stones). It's really amazing.

Unfortunately, nuclear takes too long to make safe for us to switch to it quickly enough to make a change. It takes almost 20 years per plant.

On paper it might seem a good sollution, but nuclear energy is not 100% safe and given the huge impact on both mankind and environment (often in terms of many generations), one needs to be prudent. It's much easier and safer to work with a broad spectrum of renewable energy as there the risks of failure have fewer consequences.

For the record, even including every single nuclear reactor failure, nuclear is safer than any other energy source in 2017 per watt-hour generated if you take into account everything that is involved in setting up the system. 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.

Plutonium-239, a nuclear power by-product, has a half-life of 24,000 years, 12 times as long as the length of time between Christ's life and now. How can anyone have any idea that any particular location will be geologically and politically stable for 24,000 years? Or indeed, even if somewhere stays geologically and politically stable, whether our level of civilization will remain technologically capable of continuing to contain the waste anyway? After 24,000 years, the plutonium doesn't even become safe - it just becomes half as dangerous.
+1
level 78
Apr 13, 2019
Pu-239 does have a long half life and it would be harmful if all absorbed at once but firstly it will radiate half its mass over 24000 years so at any given moment the quantity of radiation emitted is small and as an end product of nuclear reactions it is only 0.8% of the mass so if you have a reactor using 1kg of fuel you may have 8g lying around after.

I think it is important to realise that the precautions taken around nuclear energy and nuclear waste are sometimes possibly more than is necessary. Radiation poisoning is obviously bad and is rightly avoided where there is nuclear power, but it is probably less a danger than some people imagine. It is also possible that a more permanent solution may be found to the problem of nuclear waste than is currently possible, meaning that nuclear waste will not necessarily need to be looked after as it is today for periods of thousands of years.

My thoughts taking the quiz: "66.6 % increase, largest in the top 10. It has to be a quickly developing, industrializing country. Brazil, Indonesia, Turkey etc" United Kingdom?! Why such a low capacity before and such an increase during 2015?

Pretty easy. Just thought of what would lend itself to a country having a large reliance on solar energy. Quickly came up with 1) large geographic area. 2) large energy demands. 3) highly developed/industrialized. 4) low fossil fuel reserves. 5) sunny weather 6) forward-thinking energy policy.

If you could tick off at least 4 things on the list chances are the country is on the quiz.

Of those I would say 2, 3 and 6 appear to be most important. Otherwise Germany, Japan, France, the UK, Spain and Italy wouldn't be here. Though actually 4 may apply in some cases there too. But for the other four yeah geographic area plays a large role I expect.

It is a great thought that solar power will be the answer to all our energy problems. Unfortunately the reality is not so. In the UK it is a help that's for sure, but the amount of energy needed is growing daily and it would take so much renewable sourcing that it will be fifty or more years to get up to 50%. There are currently six nuclear projects in development and In the short to medium-term gas is expected to play an even more significant role in the UK’s energy mix. Also it seems unlikely that solar PV projects will be eligible for participation in future CfD allocation rounds.

I don't like to be a naysayer, but I'm with you on this one. Going solar is great, but I also think we need to put more emphasis on how to lower overall demands for energy rather than find more ways to meet growing demands. Do we really need bigger cars, bigger houses, bigger commercial buildings, etc? Solar helps us leave a smaller footprint, but it's only one solution to the problem. I grew up when our big cars got eight miles to the gallon but no one cared because we could always find a gas war where gasoline was 19 cents per gallon. We grew up with the idea that energy was limitless, and good living meant a bigger house, bigger car, more TVs, etc. I hope the next generations are better at embracing the "less is more" attitude and will be more conservative of what we have in addition to finding ways to generate more.

Back in 2005 I visited Australia. I thought back then that Australia, with its huge wide open areas of land along with the copious amounts of sun, would be ideal for solar power. I'm surprised at how sluggish they have been to adopt the this technology, when a country like the UK, with it's very unsunny climate, has more capacity.
+2
level 79
Apr 24, 2017
The UK has about 60% more capacity and 200% more people. Back of the envelope calculations say that Australia produces about twice as much per person. In addition Australia has loads of coal reserves that are easily recoverable. The UK doesn't have that luxury any more.

I'm not sure I agree it's a 'luxury' but it's a perfectly rational economic option. There are plenty of coal reserves in the UK but they're not economically viable to be deep mined and it's not socially acceptable in a densely populated island to have vast open cast mining, thank goodness.
