This glossy attempt to sell renewables omits the fact that, as intermittent sources, they depend on gas turbine plants for backup power, and that's just pumping more greenhouse gas emissions into the atmosphere. Nuclear doesn't, and it's reliable and statistically safer than all other energy platforms...check it out.

With all due respect, rad waste is, by strict government regulation, safely stored at all facilities. Unfortunately, fears are greatly exaggerated, and next generation reactors, such as molten chloride salt fast reactors and other breeder-type models are designed to use spent nuclear waste as fuel, thus minimizing further the waste footprint. You may be surprised to learn that waste from coal plants is highly radioactive, as it is unregulated. Methane leaks from fracking natural gas contributes 10 times more atmospherically-harmful pollution than burning the gas itself. Carbon-free nuclear is a million times more energy-dense than solar or wind.

All types of power have alternative backup. It's how SA made the change so fast because we already had renewable backup.

Maybe because it is not efficient. Yes it would create jobs, but you need something in return to pay those people. Solar panels take up to much space for what little they produce. Wind turbines cost so much to build, it would take 50 years for them to produce enough to pay them off. Most all the green energy is funded by the government, meaning tax dollars pay for it. Nuclear is the way to go.

Power can be just, or even more, reliable than the grid! You just need the right set up by professionals to take advantage of your location.
đeri662 7 months ago
@Haliburton Solar and Wind Of coure we need backup generators, but this isn't clean and sustainable then. The same problem happens in the power grid, just on a massive scale, the need for controlable and dispatchable power is always there.
Haliburton Solar and Wind
@đeri662 You're right! All of our off-grid systems are set up with a back-up generator. When there is no sun and/or wind, the generator comes on and charges your batteries.
đeri662 7 months ago
Just 2 days of cloudy weather and low wind could drain your batteries, even if you oversize your system.

Solar power runs out at night and wind power runs out when the wind stops blowing or even when the wind blows too hard. Hydropower runs out during drought.

Yes, off-grid is probably not the best idea. You would need some backup like a diesel generator, which isn't exactly clean.

When we inevitably go fully sustainable and use geothermal, biomass, wave energy, tidal energy, solar and wind, cheap stable power will be the norm by ... 1: Using many renewable sources as listed above as even on a windless night the others are unaffected. 2: Using suitable energy storage like batteries, pumped water, liquid air, biomass, hydrogen gas, molten salts, compressed air, pumped hydroelectric power, flywheels and many more. 3: Trading energy over large distances, across continents then eventually the globe. This would even out supply and demand. This is one application that capitalistic free market economics would be most helpful by quickly managing demand and supply at all levels of electricity supply from micro grids to the largest scale. No new technology is need to make this happen as they are all currently in use, many for years As promising new technologies become available they then can be easily integrated into a modern smart grid systems.

Roadster 2.0 go's from 0-60mph in 1.9 seconds - making it the first production car to accelerate to this speed in under two seconds. It will also go from 0-100mph in 4.1 seconds and cover a quarter mile drag strip in 8.9 seconds. In addition to this it has a range of 620 miles on a single charge which is almost double what the Tesla Model S has, thanks to its 200kWh battery. Battery technology has come a long way and is improving rapidly.

Expect cheaper costs with your home’s energy consumption in the long run with generating power method “boma fetching unique” (Google it). Its an excellent place to start saving money by making some small adjustments in your house. Whether you would like to save planet earth, or you`re interested in ways to decrease your power bills.

Even if climate change is not real we will still run out of oil in the next 50 years at this rate so we need to switch to renewable energy or nuclear energy.

SOX and NOX are removed via filters in coal plants in the US now, there is no worry about smog anymore. Also we have 200+ years of fossil fuels. We should be able to make fusion viable by then and won't have to worry about electricity. In the mean time nuclear is the safest (deaths per kwh BY FAR), runs 24/7 and is cheap.
Gregory Samuel Teo
while fossil fuels are finite, technology has also made it possible to extract such fuels from previously impossible sources (e.g. shale oil). it is more plausible that oil companies and the OPEC cartel want oil prices to be artificially inflated so they can milk this resource for every cent of profit possible. on the flip side, this does mean that renewable energy has a chance to compete with fossil fuels on price.

What about nuclear fusion?
Lewis Doherty
Lewis Doherty Year ago
Nuclear fusion will likely not be available for decades, if at all. Nuclear fission is safe, because no one will build the Soviet style Chernobyl plants, which no utilities plan to do or would regulatory authorities allow them to do, and no one plans to build 1960's style plants like Fukushima and Three Mile Island. The newer designs don't generate hydrogen which could ignite and explode like as what happened in Fukushima. Unlike Chernobyl, which was graphite moderated (carbon), no graphite is used which would catch fire spreading burning radioactive materials. The newer designs will consume waste from the older generation reactors. Chernobyl had no containment structure. Fukushima had no great containment structure. Then there are the Thorium salt designs which operate at a low pressure, are self regulating and can't disperse much of any quantity of radioactive materials into the air.

Google+ Sucks! I did not come up with this. The idea is that objects in the solar system move so much as time goes by, that as more time goes by, the more probable it is that an object in our solar system will crash into us (eventually). the sun has billions of years to go, it is estimated that something will crash into us in about 40 million years or so. I'd look for the source, but your kind words disuade me.
Bethesda sucks, but Zerglings still are cute.

Mark Lo so the oil giants who used the same scheme are ok. Renewables are on par with oil and gas, yet they don’t have pollutants and gives the user more independence, and can last indefinitely, yet your reasoning is to still go with the one, oil companies, who schemes you earlier, controls/manipulates prices, and is withholding the expansion in technology within the energy sector. How are they withholding technology, because chemically speaking you can only hold a certain amount of energy with a gallon of oil, while batteries can keep getting denser and denser and more efficient simultaneously. Imagine the applications of having a car with 1000 km of range, no pollution, no loud engine sounds, no paying for gas.
