pfft fish are lame.

It's true.

why don't we just use all the extra Chinese people and make them turn a big crank connected to a generator
It would be more efficient to just throw them in a big furnace as fuel for a generator.
Atleast then you save on food/water costs.

Solar Farming is good and it shouldn't be ignored, since it is a good way to provide power.
But there are more efficient methods for large countries.
Wind power isn't bad, but it's not majorly efficient and uses a sizable amount of resources and man-power to construct.
Geothermal power is the most efficient method, but is only of use in areas where geothermal hot spots are accessible, such as Iceland.
Tidal Power is also quite efficient and can provide a consistent amount of power.
They're also much easier to construct. They're not as helpful however for large countries (such as America, where most of the country is landlocked) or landlocked countries. Island countries could make great use of it though (UK doesn't use enough, when it should).

But really though, the absolute best energy source, although strictly speaking it's non-renewable, but is atleast fossil-fuel free, is Nuclear Energy.
It's very safe and very efficient. It's got an unfortunately negative stigma attatched to it in the public eye though.

What should be done is that Nuclear Power should provide the backbone for a country's energy, while Tidal, Wind and Solar should be used to maximise gain where possible.
Equipping most buildings with Solar Panels would do absolutely no harm. It might not cover the building's energy consumption entirely, but it does make a dent.
Geothermal should be used where available, as it's a very good energy source to.

Or instead of building immense structures that harvest very little energy for a very large capital investment cost, we can just build nuclear reactors that produce stufftons of energy with relatively little waste that is actually contained rather than spewed into the environment. That will work just fine for the next hundred years until we develop nuclear fusion technology.

doesnt almost all the energy we use already come from nuclear reactors?

Unfortunately not. Most comes from burning coal or oil. A large portion also comes from natural gas, which is better than the former two but inferior to nuclear.

this would actually work


just take all the gas from jupiter  :cookieMonster:

Assuming that you're referring to electricity generation rather than our total energy consumption, we do not use oil. Coal is currently the largest fuel source for electricity, followed by natural gas, which is poised to overtake coal within the next 20-30 years.

Nuclear generates about 20% of our electricity today, and that share will decrease as time goes on.

Nuclear energy's capital costs are extremely high. Hell, it's the reason nuclear isn't being built in the US, along with the fact that we can't decide on a place to store the waste.

Yes, but as of 2011, the wholesale costs for nuclear energy per megawatt hour were less than a quarter of coal and natural gas. Also, most nuclear waste could be recycled if there weren't so many restrictions.

Sure, it costs a lot up front, but it is still a better choice.

make it moveable. that would only be a problem if it were stationary. so it would float around on its own most of the time, and when necessary one of those barges op mentioned would tow it a little to keep it out to sea
not saying I agree with the whole idea though

If we work on getting fusion to work better, we could use that as an amazing energy source.

True, the costs of operating an already built plant are much lower than coal or oil, but we're talking about building new plants. The levelized cost of a nuclear plant today, according to the EIA is 108$/mwh, compared to only 66$/mwh for an advanced combined cycle nat. gas plant.
Of course, nuclear is brilliant in terms of CO2 emissions, and if there was a carbon tax then maybe nuclear would be much more attractive, but as things stand today, nuclear isn't an appealing option.
Also, most nuclear waste could be recycled if there weren't so many restrictions.
Uranium is so damn cheap that we're not gonna recycle fuel. There may be some restrictions as well, but costs are likely the main driver.

Yeah but the fuel that powers nuclear energy has such high energy density that it is inconceivable that we will ever run out of it. The same can't be said about coal, gasoline, or natural gas.

The idea of floating an extremely expensive, intricate, and huge piece of electronic hardware in the ocean is on the highest level of handicapped. First and foremost, this entire idea is stupid from an ecological standpoint. Many forms of marine life depend on the atmosphere for their survival. While this could conceivably kill tons of mammalian marine life such as whales, manatees, seals, dolphins, and polar bears that rely on reaching the surface for air, the most dramatic consequence of covering up a massive part of the ocean's surface with a hunk of metal comes from its effect on microorganisms. One of the most important types of marine life are plankton, which are divided into two major groups, zooplankton and phytoplankton. The latter is an autotrophic plant organism that uses aqueous carbon dioxide in the ocean to perform photosynthesis. By blocking out the sun, it would create massive 'dead zones' with no plankton, which in turn would kill basically everything in that part of the ocean that can't move fast enough to reach the edge of the panel.

Second of all, this makes no sense from an electronic standpoint. Storing all the produced energy in a bank on the panels is logistically impossible, and there's no reliable method of transferring large amounts of electric current wirelessly, so transporting it by wire is pretty much the only remaining option. So it would create an entirely new issue of finding some way to transport the energy using cables miles and miles long without them getting stuck on anything, corroded by the sea water, or tangled up by sea currents.

Third, there's no sovereign borders outside of economically exclusive waterbodies, so how would you handle when someone's trade route gets in the way of your massive solar panel raft thing, or even more likely, the massive cable system branching off of it? Since these are international waters and you're essentially forming borders that countries cannot physically pass, you're also violating the United Nations Convention on the Law of the Sea.

As you can see, this entire idea is a complete ecological, logistical, and diplomatic nightmare and there's no reason why anyone should ever try to implement this.

solar energy is not a viable or efficient resource

i thought this was common knowledge

Yes that is absolutely true, but I don't see that having much bearing on what electricity plants we're going to build today. It's not looking like we're going to run out of fossil fuels in the time frame I'm addressing (20-30 years).
