The main renewable technologies — such as wind and solar photovoltaic — are drastically reducing their costs, such that they are fully competitive with conventional sources in a growing number of locations. Economies of scale and innovation are already resulting in renewable energies becoming the most sustainable solution, not only environmentally but also economically, for powering the world.
For these reasons, producing electricity through wind energy and its efficient use contributes to sustainable development. This was the headline in the New York Times on 4 April It turned out to be a premonition, since, 80 years later and electricity is being supplied to millions of human beings in the world from renewable energies such as solar.
Humanity has now declared its readiness to accelerate the transition to a low-carbon economy, conscious of the finite nature of fossil fuels and their prejudicial effects on the environment as the main cause of global warming. Solar energy, on the other hand, will never die of shining, since the Sun still has 6. Indeed, in rather less time, solar technology in some countries has evolved to compete with conventional sources of electricity generation.
Additionally, the conditions for the development of solar energy could not be more perfect: the Sun bathes the Earth hourly with enough light and heat to fulfill global needs for a whole year ; in other words, solar radiation can satisfy our energy needs 4, times over.
Well, the words of German solar energy scientist, Dr Bruno Lange, back in , have been proven right.
