With the increasing development of human society, the demand for energy is also soaring, and the traditional fossil energy is facing the progressively serious problem of exhaustion due to continuous exploitation. And the environmental pollution brought by conventional fossil fuels, global warming and other serious impacts related to the future fate of human beings also constantly force human beings to explore clean energy.
Solar energy irradiated on earth is significant. Solar energy illuminated on the planet in about 40 minutes is more than enough for the overall energy consumption of human energy for a an. Solar energy is almost inexhaustible. And solar power generation is clean for sure and does not cause public hazards. Therefore , solar power generation is known as the ideal energy source.
Getting electricity from solar energy requires photovoltaic conversion using solar cells. It is different from other power generation principles in the past, including:
- Clean and harmless, no risk of burnout;
- Not limited by resource distribution and geographic environment;
- It can generate electricity nearby when electricity is needed;
- It takes less time to get energy and it's energy-
Approximately one billion people do not have access to electricity. While progress in reducing this figure has been steady, it is still likely to be d 'at least 870 million in 2020. Grid extension is part of the answer to the question of how to bring electricity to these people, but it is not the only one. . Many countries in sub-Saharan Africa and South Asia, which account for 90% of the world's unelectrified population, are also exploring off-grid solutions, including solar home systems (SHS). The same is true for Caribbean and Southeast Asian countries, which account for most of the remaining unelectrified population. Global SHS market grew by 23 % per year since 2012, representing more than four million units installed.
Tom Fyans, director of campaigns and policy at CPRE (Campaign to Protect Rural England), which campaigns to protect the countryside in the UK, he called on the government to develop a strategy for the installation of their solar panels, including prioritizing rooftops. “Hundreds of thousands of homes, shops and offices becoming an upgraded rooftop renewable energy network is a vision that the whole country could adopt.
Solar energy can not only be used as an essential source of electricity to solve the energy shortage, but also allow us to achieve net zero emissions. Energy Solar is a key element in the IEA's scenario that the world will reach net zero emissions by 2050. The energy source is expected to account for 33% of global electricity production by then.
In truth, the new energy sector is probably one of the best positioned to weather the greatest global economic turbulence due to a distinct macroeconomic trend that sees Western countries accelerating their construction of solar energy.
