One of the major concerns of governments worldwide is to guarantee the availability of energy supply, even if energy is an ubiquitous commodity at the distance of a click. So is sustainability, as the COP21 conference committed to a faster decarbonization.
The introduction of renewable sources in the countries energy mix prompted for relevant premium prices in power purchase agreements, namely for wind and photovoltaic parks. As expected, the technology evolution brought the wind energy overall costs (also known as LCOE or Levelized Cost Of Energy) to similar values of those of gas, coal or nuclear, allowing it to position as a competitive source of energy, wind allows it. On the same direction, photovoltaic electricity generation is also becoming affordable with an important twist: its price and scalability allow for consumers to produce their own energy. Add a storage battery and everyone gets its own electricity 24/7.
