How Solar At High Altitudes Could Power Entire Countries, Even In Winter
How Solar At High Altitudes Could Power Entire Countries, Even In Winter
SUMMARY
The text says solar energy is really useful, fast and cheap, but it also has problems as there isn't sun all year around all the globe. Eventhough that's true, it seems new researches have made public that even zones far from the Ecuator at winter can take advantage from it.
It is necessary for there to be high mountains, though. In high mountains there's less athmosphere, so by putting them there and placing them in a more vertical position they can be as effective as in low places in summer. In fact the difference of energy between lower places and higher places decreases with height. By leaning it in a more vertical way, it receives more energy in winter, when the sun is lower, and less in summer, but eventhough the total amount of energy through the year decreases, in winter, that it's when it's more necessary, the energy that it gets is greater, so it's worth it.
This system allows clean energy to be produced in winter even in countries where the sun isn't too strong or doesn't show much at all. It uses hydrogen, instead of batteries, to storage the surplus energy from the summer and burn it in winter for it to supply heat and electricity. It is belived that buildings can be powered by solar energy all year.
One building in Sweden, which doesn't get much sunlight in winter, is already using this system.

TEXT COMMENTARY
After reading this text I can tell the world is trying to take care of the planet. If you can get a whole year clean energy in places where that energy isn't abundant, then you can tell that almost every country in the world can use clean energy and/or reduce carbon emissions. We are in an age of progress, we can evolve without damaging the planet, we can live without damaging the planet, so: why not live that way?
Renewable energies are abundant and really close by. We are slowly but surely introducing them more and more each day in our lives. Our planet has still an oportunity to keep living. Let's allow Earth to keep living.
