🎬 In 1 hour the sun gives to the earth the energy consumed by all humanity in 1 year. ☀️



⚡️☀️ Solar energy has the potential to meet our energy needs to a large extent, provided that it can be converted in an efficient and profitable manner.

♻️This is what is at stake in the current development of the two main ways of using solar energy: thermal and photovoltaic. The former uses the sun's heat directly, while the latter converts solar radiation into electricity.


👍 The advantages of solar energy:

- Renewable, inexhaustible energy that does not emit greenhouse gases

- Easy to install, technologies are constantly improving and becoming less expensive

- Energy available all year round and all over the world

- Energy independence from fossil fuels and foreign countries.


👎 The minuses of solar energy:

- Intermittency: electrical production depends on sunshine. Without sunlight, there is no electricity or heat

- Photovoltaic panels contain toxic metals, recycling to be improved

- Low efficiency

- The manufacture of the panels is not very ecological, leading to the emission of greenhouse gases


⚡️☀️🌎 Currently, solar energy represents only 2% of the world energy production.
