Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

.. even with high prices. The limits comes from a  question of scale. Doubling the total primary energy with wind means multiplying by factor 100 (or more) the present output of wind energy. This is impossible in the next 15 years. It is a question of building factories, mineral resources, input energy. Not space or price.

Sun is even more impossible since the factor is around 10000 and there is a huge initial investment in energy (you need the solar roof working for seven years to recover the enrgy invested).

So right now they are not possible alternatives for doubling primary energy.

Wind with very high prices and after 20 more years of research and capacity building, it would be possible. Not in the next fifteen years.

At least, this is the number I have. I would love to be wrong, believe me. With huge investment and all the resources available I just can see a 10-fold increase  for the next 15 years in the production of wind. This would be more than enough to cover for gas and oil in primary energy.

Please, any input that would show how to make the 100-fold increase with present technology, please give me a link. I really want to be wrong

A pleasure
