Towards 100% renewable energy supplies…

The switch to mainly renewable energies offers countries without and with fossil energies more chances than threats. For a mid European country as Switzerland we can save annually 13-15 billionUS$ (260-300 BillionUS$ in 20 years) instead of supporting countries as Russia, USA, Saudi Arabia, Lybia, Nigeria etc. We can be less susceptible against blackmail and can spend the money in our country for a sustainable energy supply with less CO2, less costs and create jobs in Switzerland. Many detail problems has to be solved to be independent from fossil fuels and nuclear power. But still now we have all the needed technologies. No doubt in 2050 they will be cheaper more efficient and more power full. All we have to do is do start!
