Wind turbines are not that great for the environment as they are killing thousands of birds both on and offshore. a hypothetical question if everyone goes onto ground source heat pumps will it start cooling the earth?  

 

The numbers are quite clear on this, the total deaths caused by the pollution from equivalent output of coal power far, FAR outweighs the handful of sparrows who get smashed in by spinning blades. It's like... fractions.

it's not just a handful of spuggies it's all types of birds and thousands each day even if one turbine accounted for one bird each day its a hell of a lot

Once again... the numbers are clear. Coal kills more than wind, thus it fails as an argument against. 

 

Google that shit if you want, I'm not going to pull the numbers out my ass.

And this is where too much weight is given to the vociferous ‘green’ agenda imo.

We require electricity - unless human populations decrease (which wouldn’t be a bad thing in any way, but it’s not going to happen any time soon) there will be a continued need to sacrifice a bit of flora and fauna to fuel the demands of our race.
There are many ways in which we can generate ‘clean’ electricity - the most obvious and dependable one for our island nation with one of the world’s greatest tidal ranges would be to harness the power of the tides with estuary barrages. This has always been a non-starter though as it would disturb existing ecosystems in one way or another, and no politicians have the balls to back such a scheme as there would be uproar from the tie-died green-haired nose-ring minority.

We are in a ridiculous situation whereby new industrial buildings (and new houses for that matter) aren’t made to have solar arrays on the roof as a planning stipulation - hundreds of acres of wasted space a year are thrown up all over the country. Developers would absorb the costs (and in reality probably benefit from the investment long-term) so it would theoretically be cost neutral to the government. Firms/funds would undoubtedly buy in with localised battery storage to sell back to the grid at night/during peak demand.

No because the heat is solar heat (plus a small amount of geothermal heat escaping from the core) that has been gained in the first few metres of soil during the summer and would have radiated away in winter. The pump just moves it into the house where it also is lost from and radiated to space.

It is actually practical for a home owner to do this now, using a battery to actually profit from off peak charging and sending it out at peak. It's a form of arbitrage where the buying in price is a quarter of the selling price but separated by 12 hours.

Never seen piles of dead birds under any of the turbines I have been around....

There is a massive area of the country built over, I reckon all new build houses should have 4 or 5kw of solar panels with batteries - enough for the house + a little bit spare to sell on, all office blocks can have the same.

That’s because this is an urban myth that was debunked decades ago.

In Feb 2022 the BBC Science Focus reported . . . . . .

 

. . . . .

estimates suggest that between 10,000 and 100,000 birds are killed by turbine blade strikes annually in the UK.

That’s a lot, but it’s worth noting that approximately 55 million birds are killed in the UK each year by domestic cats . . . . . .
