In my place, DAMs are putting most of the required power supply. At the same time it has started raising environmental impact concerns and due to age of some of the existing ones, the risk of accidents is also there. Yet the government is not able to adapt to an alternative source other than national grid (which is fed with coal plants). There were announcements for subsidized solar installations at home, nothing went smoothly.

Good job Matt. I've been a hydro engineer for over 40 years. I say all turbo (rotating machinery) electrical generation is dead, at least I hope it is. This includes hydro, wind and steam. Nothing can compete with solar and battery storage. Lastly I'm not a big believer in "new" hydro technology. Hydro turbines have been 85-90% efficient for well over 100 years, not a lot of room for improvement. I've seen so many high-tech turbines come and go, most getting 3-5% more efficiency only to fly apart after a few years. Tidal and river flow turbines are simply a waste of time and money. Too much machinery for too little power. None of this will ever be economically viable.

I’m a great advocate for hydropower. It is true that there are environmental impacts but they don’t come close to the dangers of fossil fuel or nuclear. They work day or night and without impact from the weather. The new designs will reduce the environmental impacts even more. We have used rivers for a very long time but the power of the oceans represent the largest source of power on earth. It is long past time to start to use it. I remember Jacques Cousteau talking about this in the 1960’s. Check out the power station at Annapolis Royal in Nova Scotia. It is quite remarkable, it is a dam across a tidal river which uses temporary impoundment of the the tide. The dam closes at low tide, allowing seawater to impound outside the dam. It then opens up allowing the water to flow in and make power. Once the water is up in the river it closes and waits for the tide to go out and then makes power again as the water flows out. I watched it work one day while fishing nearby. The ecosystem is strong, there were tons of mussels and striped bass around. It seems to be a great system. It supplies almost all of the power for Atlantic Canada.

If you’re going through rough times, please don’t give up. Better times are coming ❤️

I live 5 miles from the ocean. I always wondered why the government hasn't invested in hydropower. The ocean waves are a perfect energy source.

Energy storage and green energy generation are certainly important, but the fastest way to reduce emissions is by rapidly cutting energy use across the planet, and there are loads of simple things we could do to accomplish that. Specifically with regards to transportation: 1) Move to a 4 day work week from 5 reduces commuter based emissions by 20% overnight. ALL commuter based emissions. 2) Enfoce a mandatory work from home policy 1-2 days per week for office workers would reduce office commute emissions by an additional 20-40% overnight. 3) Push for more bike friendly commuter policies and infrastructure, and for every day per week a person choose to bike to work instead of drive could further reduce commuter based emissions by 20% . Biking can apply to office and non-office workers alike. 4) Improve public transportation in suburban areas which due to low population density has a serious public transit use problem. These areas require too many routes and too many stops, making the system prohibitively slow, complex, and expensive. They're so unusable that people just choose to bypass public transit altogether and buy cars, resulting in unsustainably low volumes utilizing the public transit system. However, using a combination of buses and electric bikes / scooters / ride sharing could increase distances between routes and stops by 3-4x. In effect, the bus stops can be further apart because once you're off the train, you can utilize the bike / scooter to travel the last 1-3 miles at a speed 5x faster than walking. 3 miles walking would take about an hour. 3 miles on a 16 mph e-bike/scooter would take 10 minutes. Older / disabled people that couldn't utilize bikes / scooters could have utilize ride sharing at a subsidized rate at each main bus "hub". It reduces the number of buses running, reduces the complexity of the routes, and increases per bus density. Make those buses electric, and now you've not only removed gas tailpipe emissions, but drastically reducing overall bus miles driven and total energy use. 5) One idea someone put out there was the government giving every person an electric moped style scooter for free. A scooter takes significantly less resources than building an EV, uses significantly less energy to travel than an EV. Instead of 10 kWh for the average 32 mile r/t commute, a scooter may only use 1-2 kWh. An e-bike uses less than 1 kWh for the same distance. That's an 80-90% decrease in commute energy use versus an EV. .... EVs are great, and are the future, but they still use a lot of energy which will require more power plants, whether renewable or fossil. Renewables and EVs will eventually take over, but if we want a rapid reduction of emissions today, the ideas I've outlined above could be implemented this year. They don't require the 30+ years we'll need to replace all ICE vehicles, or to accomplish the massive renewable energy and energy storage build out.

Consider designing pumped storage from Lake Erie to Lake Ontario, around Niagara Falls. 42 cm level change in Lake Ontario could backup the entire east coast for 4 hours.

Thank you!

You're welcome!

Major environmental impact of windmills occurs after they fail. In most cases they are abandoned because the cost to take them down

My distant ancestor John Adolphus Etzler in his 1830 book "A paradise with in the reach of all men" proposed the use of tidal, wind and solar energy to allow for an industrial society. Oil and natural gas is not mentions as they were not yet discovered. In Ontario, Canada electricity is often referred to as hydro.

Right when I have to do a project on Hydro! haha thx!

I like the wave energy air turbines, where the wave moves up and down in a closed chamber. The air in the chamber is pushed out and sucked back in through a turbine. I think it would be easier to maintain than underwater turbines. Also rather than placing them on our precious coastlines, you could have a sealed tunnel to the turbines further inland.

Tidal energy is an important part of our answer to global warming. It is one of the few sources which is a source of renewable energy with 1. low environmental impact 2. Minimum impact on local ecosystems 3. Capable of delivering base load. Additionally, the turbines method of harnessing tidal power, can be couple with off-shire wind to further reduce the impact of these systems.

DISCLAIMER:. I work in the hydro industry for an OEM of hydropower equipment Most of the dams in the US were originally intended for flood control. In some areas there is a push to return the water ways to their original condition before dams. This is dangerous due to flood control being removed as a consequence. Hydro power is the most power dense of all alternative/renewable power sources and can be scheduled much better than wind of solar. It is an integral part of balancing our power systems and enables wider adoption of wine and solar which are difficult to schedule and are intermittent and spikey in their output. Hydro definitely has a bigger environmental impact compared to wind and solar, but nowhere near that of legacy carbon based power generation and the impact is very low concerning carbon emissions. Combined with the flood control benefits, hydropower should continue to be a key component of power generation IMHO.

Nova Scotia has the highest ice-free tidal fluctuations in the world (appx. 50ft of water level difference between low and high tide). Two different organizations tried to harvest energy from our tides but their turbines failed because they were pummeled by giant hurtling boulders moved by the intense current. All future attempts are abandoned.

The Grand Coulee Dam in Washington is bigger than the Hoover Dam. Aside from that I'm a big fan of tidal generated power. I love that someone came up with the idea of putting turbines under water. Nice video.

Thanks

I appreciate the collaboration with Terra mater, however it would’ve been nice to have also included some of the major and surprising downsides of Hydro power in this video directly. leaving terra mater to go more in depth. I feel like I didn’t get all the information needed because of this split format. While one of the reasons I love this channel is the well-rounded complete view you strive to provide.

This is the best channel for renewables on KZread

One thing I thought of when you were talking about the cost of hydroelectric power is that dams are expensive, but there are more uses than just power. People recreate in and around the lake, and water is used for irrigation and drinking. Also, another cost is silt build-up in the reservoirs behind the dams.

Water in lakes get far bigger evaporation area then it has naturally. So basically, hydro dams drains a lot of water out of river system. It does not help irrigation at all.

The "construction phase" of almost anything generally creates the highest environmental impact. People often focus on disposal and forget construction, like when comparing paper vs. plastic bags. Plastic bags are worse for disposal, but for construction and shipping, paper bags are far worse. Some of the laws that prohibit plastic bags but permit paper bags seem blind to this - or perhaps their only goal is to reduce lasting litter.

Distributed/modular energy generation is freedom! That water rotor looks like a very promising product. Hopefully it gets the funding it needs for mass production.

Thank you. 👍

That's what batteries help with. Adding all of those sources into a single output to what we need to power it. Or backup power. Batteries are more helpful than people think. I agree with you!

Plus geo thermal! That could be a way to repurpose all the fracking crew's. Plus existing power plants could be converted to running off geo thermal steam more easily and probably more cost effectively then just shutting them down. Making the tax payers absorb the loses as they retire them. 🤔

A combination of pumped storage using tidal rivers seems like it would be a great option? Remove the need for pumps by using the tide to refil reservoirs. Turbine design seems very basic from the images here. I'm excited to see the progress of hydro in the future. Side note: Nikola Tesla's "One Way Valve" seems like it would be a perfect way of allowing tidal rivers to refil reservoirs with little to no impact on marine life. Would love someone smarter than me to comment on this :) Thanks for the video

big fan of tidal power. Can't wait to see which tech wins out. Thanks Matt.

Thanks.

There is one technology that i have for many years wondered why we don't see or hear much about, and that is geothermal. We are literally sitting on a vast reserve of energy, surely,, this has a much greater potential for long term scalable and sustainability than wind or solar.

Miami / gulf stream . They have a consistant strong current right in front of there door. Ofcause Florida also doesn't use enough sun so im not surprised.

Minesto is worth a look. Kite under water now being deployed.

It is the future. Need more projects of this type.

A balanced assessment and good to see intermittency as the key challenge for renewables. With no cheep storage options it critical we recognise the importance of fossil fuels and adopt realistic tradition timeliness rather then net zero fantasy.

Can you please review the wyze cam v3 because it’s more affordable and it now is rated ip65 I’m also considering the wyze cam

one issue not spoken about is the harsh environment, water and the other environmental elements in it causes severe corrosion and fouling, hopefully they have found solutions to this
