Renewable Sources of Energy

[KL Dubey]

Is there any data over time on actual yield vs installed capacity of wind farms in India?

Recent European data has been quite disappointing, with actual yields around 21% of installed capacity, despite locating the mills along North Atlantic coast and offshore which are usually quite windy.

Same in India - about 20%. USA 31%.

I didn't quite understand the technical aspects of the discussion. But to my limited understanding the technology can be broken into 3 parts.
1. Submarine power cables. This is eminently doable.
2. Grouting a concrete bed on the ocean floor on which the tower would stand. This too doesn't seem a big challenge.
3. Single blade turbine. Not sure why this would be a challenge.
Can others weigh in?
Thanks.

India Launches a Project to Generate Green Hydrogen Through Nuclear Power

The Department of Atomic Energy (DAE) is starting a novel project to convert two experimental reactors into nuclear power pilot plants that will produce green hydrogen.

This massive initiative intends to show off nuclear technology's adaptability and agility while also advancing India's aspirations for sustainable energy.

The Indian High-Temperature Reactor (IHTR), created by the Bhabha Atomic Research Centre in the middle of the 2000s, is one of the reactors that is the focus of this transition.

Has anyone looked into the work of toroidal plasma generators for increasing efficiency and reducing emissions?

It seems the Indian govt and the Navy is possibly interested in this tech that can be retrofitted to regular fossil fuel fired engines but only emits about 20% oxygen and zero carbon.

Based on something called a Vajra/thunder storm generator (smart) developed and tested by an Aussie on a Perkins generator (400kw) somewhere in the UK.

seems all Tesla electric cars are lying around charging stations as the super charger at the stations are not working due to double digit minus temperatures in the USA. so musk has got some homework to do..

As someone who lives in this area with one of musks car, this incident is a "nothingburger" and as usual a gross exaggeration by the media.

[sohamn]

As someone owning a tesla and living in northern part of USA, this is a fake news and nothing like this has happened. Don't trust the right or the left in usa, its fake news everywhere.

+1 , I live in colorado and own a tesla, this is a nothingburger. A lot of this is legacy auto trying to make Tesla look bad.

This is the data from the Central Electricity Authority. Thermal, primarily from coal, and some from natural gas, remains the primary source for power generation. To get a clear picture of energy consumption, this forum needs to have an active thread on fossil fuels - even though it isn't sexy.

Coal consumption has been increasing in the last 2 years after Covid (Apr-Jun 2022 is an aberration):

Thanks Mort ji

The units used in the graphs BUs and MUs is very telling... !

Net Zero gaya "tale" leney

If a country like India which is close to the equator can't generate meaningful solar power, imagine EU countries wallowing in energy transition delusion!

BTW, IMO renewable energy is anything but. Solar panels, wind turbines cost huge amount of resources to produce and don't turn into mushy compost at the end of their useful life.

[Mort Walker]

Solar power has a place. It is to provide the peak demand when nuclear and coal provide the base load. That is the only way it becomes a cost competitive solution. Wind power is okay, but it ruins undisturbed landscapes and adversely affects wild life including birds. Unlike North America, the Indian subcontinent doesn't have large areas of wasteland. Eventually, coal will have to be replaced with natural gas then transition to nuclear. This ins't going to happen before 2040. Until then koyla is king!
