- Global warming is causing a rise in sea level, which makes more coastal wetlands disappeared, more shorelines erosive and increases flood in coastal areas. Regional climate shift also brings a sever impact in agriculture and ecology. The greenhouse effect and global warming are continued at such levels might result in worldwide catastrophe and disaster, such as hurricanes, tornadoes, tsunami, flood, etc.

- Solar electric systems are also known as photovoltaic (PV) systems. While they are in operating, the PV systems produce no air pollution, such as greenhouse gases; hence, they might reduce global warming, hazardous waste or noise with the characteristic of no fuels transportation, According to the report from National Renewable Energy Laboratory, each kilowatt of PV-produced electricity offsets up to 830 pounds of oxides of nitrogen, 1,500 pounds of sulfur dioxide and 217,000 pounds of carbon dioxide yearly.
