The British government has promised to go carbon neutral by 2050 how much to generate all electricity from wind?

How can we produce all our electricity through wind and solar? These are the two most wide-spread possibilities in terms of green electricity generation. It has been calculated, that in order to power all UK homes from wind, we need funding of 50 billion.

Now while this number is huge, the British government spent over a trillion pounds last year. This means that the investment required to generate 100% of our power from wind is about 5% of one years spending. This strikes me as incredibly cheap. This investment, would allow about 4 times as many turbines to be added as there currently are.

There would obviously be other costs, such as storing electricity for when the wind is not blowing. The important take away, is that this is negligible. Indeed with debts of over 3000 billion, adding 50 more is not a big step.

More importantly, it is calculated that doing nothing could cost the UK alone trillions of pounds. If we invested this money over the next say 8 years (so that all the money was available by 2030 and all the turbines were up and running by 2035) it becomes quite a small investment in government spending terms (though it is still a large amount of money).

It is estimated that by 2050 climate change could cost the UK up to £20 billion a year. Of course other countries around the world will likely have to pay far more. The UK has the 12th highest electricity use in the world as a country, this means that while each country will need a lot of money to go fully green electricity, it is not necessary to break the bank.

Different countries will have different ways to reach net zero, and we should help and encourage this move – but why dont we start planning the necessary investment, make sure that the UK leads the way in eliminating our electrical carbon footprint?

Global warming is happening, and even with the cuts promised, we are likely to see significant sea level rises: what is this likely to cost

It is an unfortunate fact, all over the world, that people have chosen to live near the sea. There are many reasons for this, but the basic fact is that this is often the most productive land.

The problem now, though, is that all these peoples lives are liable to change. This is because small rises in sea levels could make them homeless. As much as 1 billion people live at low enough elevation to make this a threat.

Countries like Bangladesh are very flat, and it is estimated that as many as 20 million people within Bangladesh would become homeless by 2050 under current trends (this assumes that we meet our carbon cut targets. There would be many others that would be lost.

Forgetting the hundreds of millions of people in the developing world, there are famous buildings and places which should underline this issue in the west as well.

Buckingham palace would be under water up to the first floor if we fail to act. A temperature rise of 1.5 degrees C would merely bring the water level to the front door. Many other famous buildings such as the pentagon, the tower of London and Tokyo tower in Japan would all be lost.

This is all a long winded way of stating, that even with the dramatic cuts the world is hoping to make over the next few decades, many people on earth are still likely to loose their lives have their lives changed dramatically, in most cases for the worse.
