I guess you guys never heard of TVA right when you say the problems are getting power across the USA the Tennessee Valley Authority has been doing that for 50 years I'd guess also I believe so is Duke power in the North Carolina so let's just be honest with every damn body the fact that we are not using not even 50% renewable energy now is all about the money that the fossil fuels generate when you figure roughly 400 people in the world own at least 50% of all businesses they make money from the fuel from the electrity from shipping the amount of money that they will lose is astronomical and they will assassinate the next 1000 public officials world wide that even mention it

The US doesn't dam up ever river for hydroelectric power because there are other environmental concerns it would cause. *o* Dams require destroying by flooding huge areas upstream of the dam, eg 3 Gorge Dam in China displacing millions of acres of agricultural, civilian, and animal lands. *o* Dams also ruin spawning rivers and streams and disrupt spawning swims for fish. *o* Dams during construction use lots of resources to dam up thereby adding to the CO2 emissions you are trying to prevent. These are only a few impacts. The return of investment for ecological damage, makes Dams not feasible unless like socialist countries you don't care about ecology nor CO2 emissions like China. This isn't like a video game where you click and drop a dam into place. Wind as good as the leftist media has been trying to paint it. The truth is wind not only doesn't always blow leading it to only generate 24% of its true capacity but wind turbines BREAK A LOT and it KILLS birds. ruvid.net/video/video-MVHzfUWul2Y.html Also they require certain very rare and expensive elements. Same with Solar. ruvid.net/video/video-ObvdSmPbdLg.html The leftist environmentalist has been more or less lying to all of us that renewables would be enough to power all our needs when it can not. The best and consistent power with the least amount of problems is nuclear power but the media has scared us out of using it. Coal is by far the cheapest which is why its still used but it has lots of environmental problems. Lastly we are also lied to about how much of a problem CO2 emissions are. Did you know that CO2 is the smallest portion of greenhouse gases? All scientist agree that WATER VAPOR makes up 80 - 95% of all the greenhouse gases and man's contribution to CO2 emission is around 4% of its total 4% of its greenhouse gases. *If environmentalist lied to us about CO2 and renewable energy being all the power we need via using bullying tactics, what else are they lying to us about?

While it is true that Costa Rica generates 100% of its electricity from renewable sources, it is not true that this makes the country completely "green". Costa Rica still has its entire vehicle fleet consuming gasoline and therefore generating CO2.

It always puzzled me how much of China isn't modernized, yet people claim they're leading in renewable energy. Does that mean anything? the country needs at least 4 times the power of the U.S. to power their country.

Excellent video. One thing to point out about wind turbines, without getting too technical, there is Betz limit, which mathematically proves that the max efficiency a wind turbine can be~under perfect conditions~is 59%. Solar power has the most room for improvement and doesn’t have the limit of 59%. Either way, great job! Keep the knowledge flowing!

Well, only ~200 KW per unpowered dam is a very small amount of power -- maybe doesn't seem worth the cost of building into a powered dam? Oh well with that. As the exponential drop in $/W for solar continues, in a few years (2020's), everyone will start wanting to use solar for both power stations and panels on individual homes.

The UK built the "national grid" back in the 1920's and 30's. This allows the country to share power. This coupled with a distributed system means load balancing is quite easy, and adding new plants or renewable sources is also quite easy. The US needs to have some serious investment to build a national grid too. I understand the UK and US are on totally different scales! but it is not an insurmountable task, start on a state level, and then connect the states, easy... just expensive, but that's the price for the flexible, modular system that is super easy to add to or reconfigure.
Robin Lefebvre
The fact there are so many unpowered dams is probably because of the importance of private investment in the US. Given that the investment to link a dam to the power grid is huge and selling the extra energy requires licenses might be a big no-no for owners. A proper (international) grid infrastructures is one of the few things I hope I get to see in my lifetime.

My extremely conservative $800 investment on a 1.6KW windmill is barely making $1/month. Its putting out 1% of nameplate rating in an area with 8mph/ave annual wind. It took being stupid for common-sense to set in; If you don't have enough wind to blow over your house - the wind fairy isn't gonna show up and power a dozer that can push over your house. That's just the way it is in the real world.

Pretty sure a lot of dams aren't being used because they aren't worth it. Too old and inefficient, requiring too much infrastructure and maintenance for how little power they produce.

I really like your show! I'd like to help answer some of your questions about energy, dams and other items. I am an electrical engineer at a steel mill in Nashville TN. TN has a lot of hydro and nuclear power. As the engineer for a steel mill i get to talk with, and about utilities all the time. Our facility draws 55 MWs almost 24/7. Kyle stated about regulations and power sharing. I see this as the hardest items to over come. First regulations are what make our power the one of most reliable in the world. Generation stations have to have a reserve spinning at all time to cover a loss at any plant. Also you simply can not put more power on the grid than it is using, they must be in balance. With out perfect balance you create instabilities in the grid. The grid also can have harmonics and other issues, think of a car with shitty springs, you go over a bump and it wont stop bouncing. This is what a poor electrical system can do if you don't have strict regulations. Second is sharing over networks. This is a really hard problem to solve, creating loops like you are doing is asking for some strange effects in electromagnetism. For example when you ground a piece of equipment it should only be grounded at one spot. if you introduce 2 grounds, and a loop, it is called a "ground loop" and you can have currents introduced into the system, causing voltage spikes. If/when we have a solar flare, or any other magnetic event, loops that are 100s or 1000s of square miles in area would completely destroy the power grid. Also how we calculate power on flow would become really difficult, some lines could melt, while others carry little to no energy. Sizing the power lines would be a nightmare. Energy dose not just flow uniformly along every path. It can do really weird things. AC current likes to keep loops small and would travel much further than the shortest path to do so. DC current likes the path of least resistance. But resistance in cables can change with temperature, other cables around them. Also on that is that power transmitted over long distances gets lost in the wires. Just the pure resistance in the wires can eat up to 20-30% of what is produced. Some of my insight into un-powered dams, my guess is that many of them are too small/far away to make any difference or worth it to install generation. Many of these are small dams are far from needed loads, thus transmitting this power over that distance would mean almost nothing would make it to the grid before it was lost to resistance. Also many of the small dams i would guess are seasonable and thus generate large amounts of water for 1-2 months and then nothing for the remainder of the year. Again these are just my educated guesses as an engineer. Anyway again i love your videos and i'd love to have a 100% green energy source, but also one that is affordable. Cheap power is what is driving our economy, and i would only want the switch if it wouldn't put half the usa out of a job. PS green energy takes up space and we use a lot of energy so it would need to be 2 things in the future, green energy with new energy storage and people need to cut energy use (not as likely). Its takes so much energy to melt steel, that does not change. If you like having steel for buildings it takes energy to make it. The cheaper the energy the cheaper the steel. the cheaper the steel the more you can build. Here is a video showing green energy and its space requirements. ruvid.net/video/video-E0W1ZZYIV8o.html

If a small country can do it, a small state can do it. If a small state can do it, a big one can. If a big country can do it, anyone can. Although many of those countries are not known for large industry either.

Wind and solar will never power the energy needs of the near future. the only quick and safe way to do it is with THORIUM MOLTEN SALT REACTORS. Please check it out. Also look at U-TUBE Road Map To Nowhere by Conley and Maloney, it tells the whole story.

A few families use up electricity freely and end up getting a $200-$500 energy bill. There are times when even a rich family can`t seem to afford amounts like this for the approaching months. This is a generating power method “boma fetching unique” (Google it) to cut your electricity bill and generate your own power.

If you want to know why all dams are not powered, open a faucet. If you like water on demand then you understand why we don't turn it all into power.

That water still goes down the hill at some point, why not turn a turbine when the water needs to fall anyways?

I am going to throw a guess out there on why some dams are not used to generate power - could this be because the reservoir created by some dams is used to feed water to cities? In other words, dams would require a constant surplus of water to be really useful as hydroelectric power stations.

Even with theLayman alert taken into consideration ,the turbines don't turn gases or fliuds into energy. Its the movement of fluids that is turned into energy.

I think it's also important to point out unneccessary regulations on homeowners. Almost all cities and towns have zoning that requires you to be hooked up to the power grid. Even if you build a self sufficient home with your own energy source like solar or wind as well as your own clean and safe water/sewer system, The local government shuts you down over zoning. Energy companies lobby for these laws.

Electricity is $5/gallon at 15 cents/kw-hr (33.7 kw-hr/gallon equivalent....15x33.7=5). Batteries are around 12 cents/kw-hr to put the electricity in and out...$4/gal. Total to run car on grid is $9/gal. Put the brake on and it cost $4/gal to store that energy. It saves having to get more from grid but still costs you in battery usage. In contrast my engine can run on all fuels, including Natural Gas and battery. NG is $1/gal from house. Engine compresses NG so you can fill up at home. About the same efficiency as a Tesla, 60%. When I put the brake on the cost is zero to store the energy and the work is used later so 100% capture. Tesla 100 mpg highway, 200 city. My car 250 mpg highway 500 mpg city. Both maintain efficiency high and low speed. Otto cycle cars do not...hence low city fuel economy. So, mine to Tesla 2.5 to 1 ratio. Fuel ratio (see above) 1:9. 2.5 x 9 = 22.5 times MORE to drive Tesla. 1/22.5 is 95.5% of costs. Otto gas car. 25 mpg vs mine at 250 mpg is 10:1. Gasoline is 2.2/gal without fuel tax. 10 x 2.2= 22 times MORE to drive gasoline car. Tesla to gasoline car is 98% of cost. (2.2/9 x 100 mpg /25 mpg = .98) So driving a Tesla is a wash for fuel. People think it is 1/2 the cost because they don't pay for the battery each time they fill up. But that cost still exists.

Wind mills kill birds and Solar does too. Ruins deserts....Not enough land to do it. Need to lower use by using my engine...95% gone...makes kick butt car that can burn tires. Solar on roofs only. Wind is bad for health...frequencies. Why not dams? Water use, that is why. Water rights. Water will be MORE important in the future than energy...water wars. My engine solves both. Engine takes water from air and can distill it....No need for sewer system...stand alone. Can't with Electric. Power should be local because thermal loads are 90% of loads in house, not electrical. Heating and cooling...free...if you do it with my engine. Share energy? Challenge? Try funding my engine that will SOLVE the problem so no lines are needed for a fraction of the cost. Why be a slave to the grid? Look, 1/2 of human CO2 is .... breathing....CO2 is entirely beneficial. Look up "Murray Salby" and learn that CO2 absorbs in less than 10 months...math (Fourier analysis...remember below...) tells you this. Please stop spreading this nonsense about CO2. Life requires CO2. If I had a choice to push a button for 400 ppm or 1200 ppm I would push the 1200 ppm over and over and over. Triple CO2 and the planet will have 3 times more life. The key is to stop enslaving people and the grid is the new chains on man. Independence....not servitude.

First off CO2 helps the planet. As Freeman Dyson says, it is entirely beneficial. Can a gate half open trap half the sheep? The IR spectrum is open. Look up "attenuation of IR". What do you see? A gate half open by chance? Yah, you have been duped. Fourier, who invented the equations of heat transfer in 1820 said it right...you have to have ALL the frequencies blocked. If any is open (see graphs) then the radiation moves to frequencies that allow heat to vent. For example, CO2 resonates, energy goes back to ground and absorbs into it again. Ground that emits frequencies that don't resonate vent to space and become cold. The heat then travels over to the cold ground, heats it up again and that energy vents to space. Again, a gate half open cannot trap half the sheep. Atmosphere is NOT a greenhouse just as Fourier said in 1820. If you have a yard full of dogs can you trap half the dogs in the yard when the gate is half open? Sheep, dogs or radiation....same idea. Another example...if you have a filter and it cleans dirty water in 1 foot. You then install a filter that is twice as good that cleans it in 1/2 foot and so on. If you add 100 feet, does it make the water any cleaner once it is clean (frequencies extinct)? No! Adding more CO2 just lowers the height to extinction or the distance IR travels before it is absorbed...which is at 40 ft at 400 ppm. Again, have been duped...but why you ask? Money and power...slavery...same old reasons. By the numbers. Electricity is 15 cents/kw-hr. There are 33.7 kw-hr in a gallon of gasoline. 15 x 33.7 =505 cents or $5/gal. Battery costs you around $4/gal to put the electricity in and take it out. When you put on the brake in that Electric car and store it, it costs you $4/gallon so you only cut the "fuel" cost in half. NG is only $1/gal...duped. Total "fuel" cost for electricity is $9/gal. Natural Gas is $1/gal. Gasoline is $2.2 without road tax (same cost all around the world, btw....tax is the difference in fuel costs). In Germany electricity is 30 cents/kw-hr or $10/gal. Try heating you house with that....10 times the cost. Some real rich masters are enslaving us all, regardless of color. Denmark is 40 cent/kwhr or $13.48/gal...So much for your wind energy. Try my new engine in a roadable airplane (seaplane) car that could get 250 mpg highway and 500 mpg city on $1/gal fuel from house. Flying 1 cent/mile at 100 mph, 4 at 200 mph, 9 at 300 mph. Want to fly a 300 mph airplane some day? Engine compresses NG so you have a gas station in your house..... Tesla is 100 mpg equivalent (100 miles on 33.7 kw-hr) and around same efficiency of my engine system (60%), but is 9:1 in fuel costs. 250/100 x 9 = 22.5 times MORE to drive a Tesla than my airplane on the road. Hmm. Why pay $22 when you can pay $1? Because you have been duped! Btw, no smog. It can run on battery if you want to use roof solar, btw, but remember, batteries cost you $4/gal or 4 times MORE than just running on NG and around twice the cost of gasoline (no tax included). When I put my brake on it costs zero to store it at 100%. Big difference. Summary: you have been duped. You are being enslaved. Stop supporting slavery. Happy to be your "science" advisor for future videos....at least you will be credible. Yes, I have a Masters Degree in Mechanical Engineering...worked at Porsche...world expert in energy...Maybe you can get through to people better than I....and we can stop the insanity.

City simulators are a pretty good way to show problems with renewable energy. I remember playing SimCity and avoiding wind since the energy density was terrible compared to nuclear plants. One issue in the US is places like the Midwest, wind varies a lot from weeks of no wind over 5 mph to storms that would tear a wind turbine apart. Similar issues with solar, we can have months of sunny days but in spring and fall we have weeks of overcast days. As far as adding power to a dam it would essentially require rebuilding the dam, a lot of dams were made more for flood control to allow building in place that would previously flood once a year. Since electricity is an on demand, predictive industry it is difficult for renewables like wind and solar to reliably supply power. The issue with infrastructure is how it was built. It was done originally in isolated systems that were eventually tied together and when that happened some places were assholes about it like Texas where their interconnects use DC and the rest of the country uses AC interconnects. A remnant of this is seen if you look up NERC Regional Reliability Organizations and interconnects, notice how most of Texas is it's own RRO. In some ways having this system helps isolate problems like the 2003 blackout since you can disconnect from a region experiencing a major blackout and limit the spread assuming your region has enough generation but it also causes losses since interconnects might require transformers between grids such as Southern Ohio which uses 25kV class distribution and Indiana which uses 15kV class distribution. This leaves us with power grids are still highly regionalized since standardizing and modernizing them would cost trillions of dollars on the low end. Also, as a side note this is a similar problem with internet bandwidth in the US.
