ZnO₂ coated glass has higher absorption in the solar spectrum compared to In₂O₃ coated glass.

Infrared reflecting glass helps reduce heat losses by reflecting infrared radiation.

High absorbance in the solar spectrum for a glass cover is preferred.

High emmisivity of infrared radiation (εᵢ) is desirable in glass covers to trap more heat.

Glass blocks most of the infrared radiation emitted by the absorber.

Sheet glass has a high transmittance (τₛ) in the solar spectrum.

Ideal covers should have a transmission coefficient of 1 in the solar radiation range.

Wind energy has relatively low greenhouse gas emissions compared to other renewable energy sources.

Wind power requires more strategic materials per megawatt of energy produced than any other major power source. 

One of the advantage of wind power is that the recycling process of wind turbine materials is relatively simple

The wind blew from the west at speeds between 7-11 MPH (dark blue) about 8%

The wind blew from the west 30% of the time

The wind blew from the north and the northeast 18% of the time
