Solar energy is more green than any other renewable energy sources for the top five reasons
Photovoltaic systems are not the only energy technologies that have been branded "green energy generators." However, compared with other forms of energy, solar energy has significant advantages in secondary environmental impacts such as water consumption, greenhouse gas emissions, pollution and social impacts.
Sunshine is inexhaustible
The sun shone long before the civilization known to mankind began. Because of its reliability, humans rely on solar energy for lighting and heat. As solar energy is continuously available daily, the capacity of photovoltaic systems has risen the most rapidly among all renewable energy sources in recent years.
2. beneficial to the ecological environment
The use of solar energy does not pose a threat to life and the environment - and is very beneficial to the survival of coral reefs. Fossil fuels such as coal, oil and natural gas are highly polluting because they release chemicals and harmful elements to the atmosphere when mined, drilled or transported. The Valdez cruise spill and the BP Deepwater Horizon bombing are just two of the many reported major ecological disasters. These oil spills have caused a decrease in wildlife populations and have hit hard with local fisheries and tourism. Solar cells are made of the most common crystalline silicon in silica sand. Although some chemicals are used to clean the system's semiconductor surfaces during manufacturing, leading PV manufacturers follow strict environmental regulations and comply with industry waste disposal regulations to ensure that they do not cause lasting damage to workers' health and the environment. Photovoltaic can also reduce the impact on the land. Small PV modules can be installed on the roof, and large projects such as photovoltaic power plants are usually located in low-grade land or brownfields and abandoned mine land.
3. Mitigate climate change
As we know, conventional energy releases large amounts of carbon dioxide and greenhouse gases, absorbing heat from the atmosphere and raising the surface temperature. Since the Industrial Revolution, these have caused unprecedented global warming, including droughts, wildfires, storms, hurricanes and floods. In contrast, the use of solar energy to provide electricity through the PV module does not release any harmful gases, because the fuel source is the sun. There will only be a slight amount of emissions during the manufacturing of PV modules and the transportation of materials. Most PV systems generate 0.07-0.18 pounds of carbon emissions per kilowatt-hour of life cycle, and focused solar power is 0.08-0.2 pounds of carbon per kilowatt-hour. Are well below 0.6-2 pounds per kilowatt-hour of natural gas and 1.4-3.6 pounds of carbon per kilowatt hour of coal. Using photovoltaic cells for charging electric vehicles is ideal for preventing pollution. Some PV modules use solar energy and efficient energy systems in their manufacturing to further reduce carbon emissions during the manufacturing phase. Yingli Green Energy is the first photovoltaic company in the world to receive product certification of carbon emissions from TÜV Rheinland, a leader in the testing of photovoltaic products. As part of this, Yingli installed 39 GWh of PV modules annually at its headquarters and production sites.
4 will not cause water problems
Water is a basic human need, and water resources are scarce and precious in many drought and turmoil areas. The UN Sustainable Development Goals report states that under-water supplies affect more than 40% of the world's population and up to 663 million people do not have access to clean drinking water. According to UN-Water, agriculture has the largest demand of water in the world. Biofuels, which some call clean fuels, consume large amounts of water in irrigation and raw material processing and, in some cases, lead to conflicts over land use and water use. Hydropower stations are also called clean sources of electricity and are widely used as renewable energy sources. But homes and villages are often damaged or displaced by dam projects. River systems have been altered to affect wildlife habitats and freshwater ecosystems. Solar technology has less impact on humans and animals than hydro and biofuels. Although water is used in the manufacture of photovoltaic cells, as a responsible PV company, Yingli takes the issue of water consumption and drainage pollution seriously. They closely monitor the manufacturing and distribution processes, comply with national and international norms, and continuously measure their environmental impact.
5 will not produce noise
Although wind turbines perform excellently in power supply, they generate a lot of noise during operation. Residents living near wind farms react strongly to high levels of noise and many are still unable to adapt even after a long period of time. Photovoltaic modules are not considered to be polluting due to friction and sound generated by the absence of moving parts. Photovoltaic components as the sun is generally quiet. All of these demonstrate that PV modules are cleaner and cleaner than other renewables in terms of manufacturing, operation, environmental impact and emissions. Now let's talk about the advantages of solar power!
