World's largest Green Energy Generation and Storage Facility coming up in India

[sayak83]

The 5230MW renewable energy generation project with a pumped storage capacity of 10,800MWh per day (six hours per day of hydel power pumping and storage) is coming up at an investment of $3 billion by 2023.


This includes $1 billion investment in just the storage capacity and the remaining $2 billion in setting up 3000MW of solar power generation, 550 MW of wind energy generation and 1680MW of hydel power generation capacity.

I could never understand the term "green energy". The color green is the waste energy by-product of photosynthesis and plants. The sun generates a wide spectrum of energy wavelengths. Plants use mostly the blue and the red light with green light not used very much. We see plants as green, since they are discarding this color as the unused waste energy from the sun. We marvel at the discarded and useless energy of plants, and want culture to be like that.

The analogy would be someone who likes coal as energy. The propagandists decide to call the hot smoke from the stack, coal energy, since we can see the smoke from the stacks. It seems quite strange. We need more science eduction to get rid of the smoke and mirrors.

Solar power cells don't even use much in the way of green energy wavelengths. These tend to use mostly red energy. Why not call solar cell energy, red energy? This is at least scientific.

While lie about green energy instead of teach some science? Why the word game and the mindless mantra, instead of science facts?

Interesting and +ve news. However the article doesn't describe how the storage will work. It says pumped storage, so hydro, but where and how will this be done?

Probably it's near a hilly area (the state has quite a lot of hills). That provides the natural gradients needed to minimize cost.

It's not a "word game", Rip Van Winkle.

"Green" is well-recognised shorthand for industrial activity that does minimum harm to the environment which, in the context of energy generation, means renewable energy sources.

You know this perfectly well. The term has been in common use for over two decades.

But there must be mammoth excavation projects for artificial reservoirs at different altitude, or else the use of a lot of existing lakes, surely?

"Green" simply refers to something sustainable, renewable, environmentally friendly, etc. Everyone knows this.

Get up off your knees, put your critical thinking cap on, and stop allowing yourself to be spoonfed scientifically illiterate propaganda from fossil fuel industry lobbyists looking to protect profits.

I do not know the details. But clearly an artificial reservoir must be built.

Red, these days is the color of the demon. No problem if Biden is releasing IS fighters and training them for war in Ukraine (reports). US back to its ways.

Link?

In my opinion.

How are they storing the energy?

How are they storing the energy?

Pumped storage. That means you use electricity to pump water from a low-lying reservoir to a higher level one. Then, when you need the stored energy, you allow the water to flow back down and run the pump as a turbine. Overall efficiency is about 80% I believe.

This is another way to store green energy. They raise weights with motors then lower them with gravity to generate electricity.

Yes. However the article linked in this thread mentions pumped storage.

The only thing I wonder if it will be cheaper and more affordable for residents there?

The only thing I wonder if it will be cheaper and more affordable for residents there?

"According to global consultant Wood Mackenzie, the levelised cost of electricity generation from fossil fuel at around $44.5 per MWh (Rs 3.05 per unit) in India is the cheapest in the region. In China, it is $48.5 per MWh (Rs 3.33 per unit) and Australia $50.9 per MWh (Rs 3.49 per unit) among other 12 countries in the region.

The same is for solar power. In India, the cost is estimated at around $38.2 MWh (Rs 2.62 per unit), the lowest. In Australia, it is $52.7 per MWh (Rs 3.62 per unit) and China $61.2 per MWh (Rs 4.2 per unit). India’s levelised cost of onshore wind power generation, estimated at $48.9 per MWh (Rs 3.36 per unit), is also the cheapest in the region."
Why are Indians paying three to four times the cost of generating electricity?
(Kindly note that the newspaper reporting this is the mouth-piece of a political party which lost power to the current ruling party, that is why the peeve)

India gets 40% of its power from renewable sources of energy (mainly Solar / Hydel).

How are they storing the energy?

The technology is called pumped hydro. They create a large lake at a height. When they have excess energy they pump the water up to the reservoir. When they need the energy, they run the water down through a turbine to generate electricity.

Obviously not, but then electricity is increasingly generated from renewable sources, rather than fossil fuel.
