Most people probably presume that renewable energy is a really state-of-the-art thing-- keep checking out to discover why that is incorrect.

Although this might sound unusual, the sources of renewable energy that we would most likely recognise today in fact date back over four thousand years. Wind is a significant cornerstone of numerous nations' plan to turn their energy grids green, especially in nations that don't have the blessing of year-round sunlight. The first example of people utilizing the energy of the wind was around 4,000 years ago, when we captured it in our sails converted it into kinetic energy that might bring us across the seas, exploring the world around us and trading with other civilisations. A number of millennia later, the very first known examples of hydropower sprang up, where rivers and streams powered waterwheels and other contraptions that could cut stone or grind grains. It was around the very same time that we discover the first account of solar energy also; legend has it that a hero utilized a series of mirrors to burn an invading fleet, focusing the power of the sun to develop directed heat, and similar devices were utilized to light torches or fires in fantastic structures.

Although lots of people would envision that we have been burning fossil fuels given that the start of civilisation, non-renewable sources of energy only really happened throughout the commercial revolution just over two centuries ago. Even the most modern renewables are just as old. Around the time of the commercial revolution a 19-year-old French physicist produced the world's solar battery whilst exploring in his father's lab, transforming sunshine into electricity. Today, solar is the least expensive electrical energy that mankind has ever produced, and people like the CEO of Ecotricity's institutional shareholders are at the leading edge of utilizing both the ecological and economic benefits of renewable energy to continue composing this history, one that starts not in the twenty-first century, but many centuries previously.

One can quickly be excused for imaging that non-renewable energy merely need to have been the basis for all of humanity's production of power throughout our history. The Earth has gone through considerable modifications because of the quantity of nonrenewable fuel sources that have actually been burnt throughout human history. Nevertheless, that is altering, and a brand-new period of renewable energy, pushed forward by people like the founder of the hedge fund with a stake in Energias de Portugal and the co-founder of Octopus Energy's parent company, is starting to emerge. Contrary to what one may think, this is not necessarily a contemporary development; in fact, for more than two millennia, we have gathered the power of the aspects to produce energy, and the technology for producing energy from solar power is as old as the combustion engine; in almost all ways, it is a more natural mode of energy production than burning fossil fuels.
