Energy storage doesn't need to come from battery's we can use underground balloons, pumped storage, heated salt storage the possibility's are endless. We just need the government to act & invest diversely without selling it off to foreign owners that can put pressure on us down the line or raise prices.

part 1 - Demand is not the cause, it is a multiplier, which is still important. If we had 100 billion people on the planet but we had sustainable energy and resources then it wouldn't be a problem. Also they said in the beginning that demand for energy grows by 2% each year, which is caused both by increased demand by individuals, and an increased number of individuals.

Upon watching until 4:18 when the speaker was saying "We must think about how our other energy usage could be transferred into electric supply then we could've caused so much generated electricity cleanly." I SUDDENLY HAD AN IDEA! --because there was a clip of a bunch of vehicles on the road during that statement, I thought: why not generate electricity from the vibrations or whatever forces vehicles generate on the concrete pavements? (I'm no engineer though) People usually complain about the roads being the cause of heat island effect, now with that idea, at least it would provide more use right? Especially in megacities where there are always vehicles and the traffic is terrible. Also! (Idea #2) Since concrete roads are huge heat absorbers, why not generate electricity from that? An innovator should design some LITTLE contraption-whatsoever for that :)

I'm no expert or anything on this but, if a car is moving at 60mph, then there must be air going at 60mph against the surface of the car (right?) So, I was thinking if cars could have wind turbines inside the grille, and several of them, it would generate a lot of electricity that powers the car,it would be able to run purely on wind power, so that means we'll be using 50% less oil (transport) .

Why would we want to re-sequester the carbon from fossil fuel? The carbon is already trapped as a solid or liquid. We don't need to re-trap the CO2 if we don't burn the fossil fuel. Switch to nuclear and leave the fossil fuel deposits where they are. The ultimate in carbon sequestration is not to have released it in the first place.

part 2 - The carbon sink of living organisms pales in comparison to the vast oceans of carbon sink in our fossil fuel gluts. And the difference between carbon in organisms and the carbon in fossil fuels is that carbon in organisms is IN NATURAL CIRCULATION. All of the carbon that a tree takes out of the atmosphere is in the tree itself, problem is when that tree dies it is almost never turned into coal and all that carbon goes BACK into the atmosphere.

What's cheaper, building over capacity AND storage for wind and solar or building molten salt (nuclear) reactors. Even RE systems create chemical wastes which must be dealt with, either neutralized or isolated forever. Thus, the little bit of radioactive molten salt reactor wastes can be stored too. The only difference is that 80% of radioactive fission products decay into harmless elements in just 10 years, (the other 20%, just 300 years). The super long lived wastes (actinides) can be reused in the molten salt fuel, if closed cycle. Why would ANYONE want to put CO2 into the ground without first chemically fixing it! The way to deal with that is to put it naturally into the ground - as soils. This requires mega nuclear powered desalination plants for the water needed to literally green a desert. The nuclear power option could be sidestepped (to some degree) if water was instead barged from the mouths of the plentiful rivers worldwide. The byproducts: a very minute volume of nuclear wastes (comparatively) and LOTS of produce/vegetation. If greening an entire desert is not enough to store the approx 2.2 TRILLION tons of excess CO2, then, we'll have to use diesel powered heavy equipment to MINE OLIVINE rock, crush, pulverize and distribute. It's like a fertilizer which sequesters CO2 into limestone when rained on. Eventually, it goes into the ocean and also counteracts ocean acidity caused from - excess CO2. This is also natures way of geologically storing CO2 on the order of millions of years. Therefore, the discussion of liquid CO2 sequestration is merely directing people on the WRONG path (towards developing REAL solutions to safe excess CO2 storage). Renewables should, however, be strongly developed AFTER machine automation can make them and their storage cheaper than coal!

leerman22 "hot water" is a relative term. It should be noted that water discharged is typically less than 20 degrees warmer than the water pumped in, ie., if the lake or ocean is 65 degrees, the discharge is no more than 85 degrees. The law limits the delta T to 25 degrees...meaning, if the plant approaches that limit, they must lower power to prevent exceeding that limit.

Great video! I think this is one of the most important topics to consider in physics and other related subjects, as it is so current, and essential for the environment. I think that although finding a way to more efficiently produce energy is very important, the amount of energy that we consumers use is the cause of most of the problems. (If we can find away to live a good lifestyle without as much need for fuel/energy, then less fossil fuels would be required by power plants, which would obviously lead to a decrease in CO2 production.) One way in which I think we could make a big difference in reducing fossil fuel consumption, is to design and manufacture vehicle engines that can efficiently turn a totally renewable substance, such as solar power or water, into enough energy to match the energy released from combusting fuels.

This whole presentation is a bit of a flip flop, first wind energy is going from several % total production of electricity to only 1%. Electricity production in total 200 years ago was 0 (zero). Transportation 200 years ago depended on live man power, live horse power and wind. But the most important issue of global destruction is not mentioned with one word "over population". What about mentioning the green hous gas Methane? Newest studies show that Methane is responsible for 52% of global warming and it is coming from fossil fuels mainly Natural gas to fugitive migration from deep fracked geology, leakage from pipelines and distribution systems in cities and not from cows or swamps. Putting CO2 underground for huge cost and uncertenty it will stay there is foolish. We tried the nuclear way and it turned out that people like me where right 50 years ago who said it is not feasble because of the safety and the wast issue, now we know, TMI, Chernobyl, Fukushima and a unknown number of smaller icidents. Reduce population grows, install solar, wind, geothermal as much as possible, produce electric vehicles in mass production and reduce the production of combustion engines. Turn the lights of when not necessary, build buildings for 500 years and more it was done a long time ago. The list can go on. But that would mean that the greedy 1% would lose there grip on the rest of us.
