Clean and Renewable Energy Source: Unlike fossil fuels, the production of electricity from the wind does not pollute our air, water, or land with particulates or greenhouse gases. Wind is a renewable energy resource that we won’t run out of.http://www.szzkgy168.com/wind-power/

As its name suggests, a ground-mounted solar system is a free-standing solar array mounted on the ground using either a rigid metal frame or atop a single pole. Ground-mounted systems can take the place of a rooftop system when the latter isn't available or suitable. Both provide greater benefits than relying on fossil fuels for your electricity needs. Not every roof is suited for solar panels. but not every home has the extra space needed for ground-mounted panels. http://www.sun-novasolar.com/ground-mounting-system/ground-solar-mounting-system/
