Fossil fuels supply about 80 per cent of the world’s energy and 60 per cent of our overall electrical generation.
This in spite of the fact that quite a number of countries have been seriously shifting to renewable energy.
- Iceland uses geothermal and hydroelectric plants to supply 100 per cent of its electricity and home-heating needs.
- Sweden has been making bigger investments in solar and wind power, more efficient grids, power storage, and clean transport.
- Costa Rica has been harnessing the power of its volcanoes, enabling it to build more geothermal plants along with other ecological projects.
- The United Kingdom optimizes its use of wind power, with Scotland now attaining 100 per cent electricity supply to all households from this renewable source. Following closely in its record is Ireland.
- Denmark is also hitting its goal, now supplying 40 percent of their electricity needs from renewables.
- Solar power is also being exploited successfully by Germany and Morocco.
- Meanwhile, Nicaragua and Kenya have been investing a great deal in geothermal and wind energy production.
Nevertheless, the world needs more action based on current data.
According to the United Nations, public policies are one of the hurdles in the pursuit to make renewable energy a more popular alternative energy source.
Another challenge is energy storage.
Currently, solar and wind energies are among the most widely-used alternatives to fossil fuels. But these sources, unlike the traditional, can be harnessed only on certain times. You get solar only during daylight, while windy days are more difficult to rely on.
However, each renewable energy has its peak and, if those energies could be efficiently stored, then the world could benefit a lot more. It could also bring the price of renewable energy further down, thereby accelerating the global transition to cleaner and sustainable energy.
Another giant corporation that’s meeting that challenge in order to help save the planet is Google’s…
