「Global Warming」cause---Greenhouse Effect
-
As
everyone knows, the traditional power sources are the
largest air pollution producers. This pollution affects
people's health, environment, etc..
-
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.
