Environmental Cost Of Solar Panels

Solar and wind energy are often looked at uncritically by environmental proponents.

Environmental cost of solar panels.

Energy amortisation life cycle assessment lca carbon cost payback and energy payback period. Things may be changing. Using solar energy can have a positive indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. This means that the amount of energy needed to manufacture the panel is regenerated after 2 3 years of solar production of the solar panel.

The good news is that while the epbt of a solar panel is dependent on many factors the market is moving in the right direction. Bats and birds are killed every year by wind turbines.
