For billions of years, the sun has been releasing energy. The solar energy used by the earth is less than one ten thousandth of the energy radiated by the sun to the earth. Solar energy is a clean, renewable energy source. Unlike fossil fuels such as oil, natural gas and coal
it will never be exhausted (at least not in the next few billion years)
while fossil fuels are non-renewable and also produce greenhouse gases which lead to environmental pollution and climate change change.
In the United States, buildings such as offices, residences, and stores consume nearly 40% of energy and 70% of electricity, and therefore produce more than one-third of the emissions of the entire United States, more than any other economic sector. Light is the most abundant natural resource on earth. Installing solar panels on the roof can make better use of solar energy and reduce global energy consumption. Currently, nearly 78 gigawatts of solar panels have been installed in the United States, enough to power 14.5 million homes.
The booming development of solar energy-related industries has also created many well-paying job opportunities. In 2018 alone, approximately 110,000 new jobs were created in the new energy field in the United States. Installing solar panels is expected to be one of the most in-demand jobs in the United States by 2026.
"Solar One"
Solar cells can convert light energy into electrical energy. Its working principle is similar to photosynthesis - plants absorb sunlight, convert it into chemical energy, store it in organic matter, and produce oxygen at the same time. Like plants, solar cells obtain energy from sunlight. The cell used by
to convert solar energy is called photovoltaic cell . Photovoltaic cells collect sunlight and convert light energy directly into electrical energy. Solar panels are composed of multiple groups of photovoltaic cells. The more solar panels there are on the roof, the more solar energy can be converted. You must be wondering, can you still use solar energy to generate electricity when the sun is not visible, such as on rainy days or at night? At this time, it is the turn of solar battery to play its role.
Solar batteries can be used as part of a solar panel system and can store excess energy generated by solar panels for emergency use. Climate change is causing extreme weather to occur more frequently and more intensely, sometimes leading to power shortages or blackouts. In this case, it is important to have power equipment such as solar batteries.
SolarOne, an environmental organization in New York, USA, uses innovative methods to promote solar energy in some communities. For example, the organization launched the Here Comes Solar project, which installs rooftop solar panels in local communities. In addition, they also cooperate with other institutions to help some relatively poor people use solar energy.
One of the ways the "Solar is Coming" project promotes solar energy is through community sharing to provide solar energy to communities with insufficient infrastructure. Community residents can jointly purchase solar equipment, so that they can use solar energy and save themselves the trouble of installing solar equipment in their own homes.
In the United States, for nearly one-third of households, electricity bills are a large expense, and may even be one of the largest expenses in their lives. Therefore, the "Solar One" organization also plans to install solar panels on public rental housing in Harlem and Brooklyn, New York,
which will help 350 low-income households save electricity bills.
"Solar One" has also launched a "green labor training" project to provide skills training specifically for people with employment difficulties (such as those who are homeless).
