Re: Wind and Solar vs Coal, Gasoline, Nuclear

As a side note: Denmark (Birth home of Vestas, NEG Micon, Siemens WindPower etc.), now have a lot of landbased windmills exceeding 20 year lifespan. They estimated span for the installed turbines in 1995-2005 is 25-30 years! After 20 years all turbines operate solely on spot-pricing market (ie. no s...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

What do you expect from the nuclear liars? ..... c-Si Wafer thickness is 180µm. So 1m² solar cells contain 180cm³of Silicium. The densitiy of Si is 2.34g/cm³, so this translates to 421g. Not counting gaps between cells and the module Frames, but also not counting losses (which usually are reused). ...

So apparently since it doesnt solve everything, its useless or what??!?! Solar works great to offset the mid-day summer cooling peak for California from the nearby desert.

Germany’s energy consumption in 2017 by Craig Morris 11 Jan 2018 Based on preliminary figures for 2017, electricity from renewables grew by a record amount. Coal power production also fell noticeably even as nuclear power fell – despite record exports. But one big news item may have been overlooked...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

The oportunities for $0 cost will be far fewer than demands. 70% efficiency of pumped salt water hydro has already proven to be too low in a free market. 33% from intermittent electric over supply conversion to heat, and back to electric, is way too low to be cost effective.

Yes, these projects are not common, especially for high power (back up) systems of 20 + hrs storage capacity. Unless my maths is screwed, ...isnt that German project actually $0.073 /Wh ..??

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I've read about thermal hot water storage to time shift solar energy by a whole season. How efficient can this be? I have also seen daily thermal storage with molten salt which requires a steam plant to convert back to electricity at 30%. Its quite efficient. You volume grows to the power of 3, but...

That part you quote if for low-grade thermal storage ie. hot water, think you misunderstood the post.

Yes, but as i said , establishing actual costs is near impossible.. None of those figures relates to the actual "cost" of generation (LCOE).....its all " commercial/contract pricing". There is simply no way an offshore wind turbine can produce power at a cost near to even gas co-gen that Denmark ha...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I really do not understand how Denmark could have an average generation cost of us$0.04/kW when you have such a high proportion of Offshore wind and thermal generation (much of it heavily underutilised !). Thats easy - it's because of renewables. A lot of the renewables can sell with profit down to...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

...my understanding is that a large proportion (DKK 5.0bn pa), of the tax on electricity is paid directly back to the generators of renewable power.
