Energy powers everything, from lamps and smartphones to life and planets, muscles and engines, it creates molecules or splits atoms, it creates substances and products and is the source of everything. There are 4 types of kinetic energy (mechanical, thermal, electric, magnetic), 4 types of potential energy (chemical, elastic, nuclear and gravitational) and 2 others (sound and light energy) all of them necessary in different ways for the existence of life as we know it.
In the last hundred years, we become dangerously dependent on electrical energy, if we will wake up tomorrow, put our devices into the socket and nothing happens, chaos will come upon developed and developing countries: no food, no water, no communication, no google search for ‘How To’, we will be paralysed.
In the last 20 years, world energy consumption doubled because of the increase in population, from 5.3b to 7.5b but also because of the use of technology. Energy consumption per capita increasing with 50% reaching 3.05MWh/capita. Unfortunately, there are still over 1 billion people with no access to electricity, while 1/3 world population meaning China, US and EU are consuming more than half of the energy.
Energy is the world’s most important contributor to GHG emissions being responsible for 60% of CO2 emissions while also polluting the soil, water and air. We have to transit to a world with local production and consumption of clean and affordable energy. Today only 20% of global electricity production comes from renewable.
Democratising renewable energy is the solution to world energy trilemma: energy security, energy equity and environmental sustainability. For example, every 15 minutes of the sun are enough to power a year’s usage of humanity, this is the amount of wireless energy that touches the Earth, and there’s so much clean energy available out there.
