How can UK generate electricity without using coal?

there are vast amounts of options available to us, my favorite is tidal lagoons and solar stills

in short a circular area of the severn dammed up, when the water rises it can let in the water gradually, then the water can flow out gradually as the tide recedes. this evades the problem of only having power when the tide is fully in or out and would be far more efficient for the space enclosed.

wind power is a partial solution but on a windless day we would have no power so we couldn't rely solely on wind farms.

photovoltaic cells are quite reliable and will give energy even on a cloudy day, but only 10% of the energy that hits them as light is turned into energy and so is only really viable in the small scale projects like on a house

for larger projects where solar energy is being used solar stills are much cheaper to set up and about 30% efficient, 3 times that of normal solar panels, they work by refracting the sunlight to a tube of molten salt, this is pumped and coiled in a container full of water. when this water boils it is used to turn a turbine which then turns the genarator.

if lots of land is availiable a full solar thermal plant could be considered, this uses vast numbers of huge mirrors to refract the sunlight so it focusses on a point that can rise to four or five thousand degrees. simply huge amounts of water are pumped through this point in heat-proof pipes. this instantly vapourises in the heat and as before is used to turn a genarator.

I've been working on an alternative energy generation project at Calpine's Metcalf Energy Center in San Jose, CA. The idea is to extract energy from anthropogenic emissions using an Elliott low pressure steam turbine and a generator. The average human can exhale into the steam generator unit and produce about 21.5 watts at 12 to 25 volts depending on the person. The power is small compared to a bicycle generator which produces on average 300 watts at 12 to 25 volts DC.

Several weeks of testing went by and I could not generate more than 22.3 watts from anthropogenic emissions. I needed a more powerful person! But who, who could produce enough steam? And then it hit me!! San Jose, CA is loaded with screaming liberals! All I had to do was hook a liberal up to the Elliott low pressure steam turbine and say something to set the liberal off.

Here are the results:

Statement to liberal: Output:

"Your Medical MJ card is not valid." 785.5 W@ 12 to 25 V

"Please fill out this job application." 811.5 W@ 12 to 25 V

"Your monthly SSI check will be reduced 25%." 963.5 W@ 12 to 25 V

"Bush Tax Cuts." 1181.5 W@ 12 to 25 V

"When it comes to Rufus and China Cat, you ARE the Daddy."1256.8 W@ 12 to 25 V

There are plenty of different fuels that are used to create electricity from nuclear, other fossil fuels such as oil, water and even wind. I have recently watched a few documentaries on new wind farm ideas which will hopefully be opened out in sea, near the channel, where they have huge inflatable windmills attached to turbines under water, which should produce alot of energy, hopefully also freeing up space on land. Hope that's answered your question

Nuclear Power is the best option. It is cheaper than Solar and Wind. It requires a lot less space to produce the same amount of power. It produces no green house gases. It is much more reliable because it produces power 24 hours a day.

Put all the environmentalist onto exercise bikes attached to electric generators.

Or use environmentalist for fuel instead of coal.

nuclear power. 20% of power in the u.s. is nucs. we have 11 plants in illinois. i wish we had more. most of the bad press about nucs is left over from the 80,s. france has the right idea. the movie "the china syndrome", made in 1979; was laughed at by reputable physicists and nuc engineers when it was released.

build nuclear plants like your friends in France and Italy have:

Develop thermonuclear fusion technology:

Have BP Drill ultra deep wells to tap the heat of the earths core and use it to generate steam:

100,000,000 gerbils runing on wheels:

Use human beings as batterys (per the Matrix)

Build Nuclear Plants:

Have all the AGW alarmists put their woolly socks on, hold hands while hooked up to a wire and have them quickly rub their feet on a carpet. It saves the planet and keeps them busy while the rest of us go on with more important tasks.

Nuclear, gas, wind, hydro, marine, tidal, geothermal, solar, biomass, waste.

Solar's pretty useless in the UK, but we could have solar panels in Africa or Italy piping power to us.

Rough figures for one possible route from my research (I spent a year in a physics lab working on solar cells and we talked to various energy engineers):

~30% wind

~10% biomass/biogas/waste

~5% tidal

~5% marine, hydro

~40% nuclear

~10% gas

Would be a pretty clean grid.

I don't really know much about UK energy. But these are my opinions.

Nuclear Energy: - It doesn't take lots of space and produces lots of energy for a cheap price!
