While travelling outside the city a month ago, I was pleased to see windmills on the way. I asked why they were not uniformly placed or present is great numbers – to which my spouse replied that you cannot plant windmills anywhere you want and that it requires careful observation and analysis of wind patterns among other things.

I have heard engineers working on solar power (or ones who have studied it deeply) talk about the problem of cost-effectiveness of solar power. However, here’s a developed country that has invested intelligence, capital, technology and commitment in making renewable energy a significant portion (going to 30 %) of its total power production. Germany’s actions have brought down the price of technology for renewable-energy products to a great extent and the model is a great one worth emulating. Tells us that if you are up to it, you can bring about constructive change.
