In late 1992, 1,700 scientists from around the world issued a dire “warning to humanity.” They said humans had pushed Earth's ecosystems to their breaking point and were well on the way to ruining the planet. The letter listed environmental impacts like they were biblical plagues — stratospheric ozone depletion, air and water pollution, the collapse of fisheries and loss of soil productivity, deforestation,  species loss and catastrophic global climate change caused by the burning of fossil fuels.

How Much Do Solar Panels Cost in the U.S. in 2017?

In 2017, most homeowners are paying between $2.87 and $3.85 per watt to install solar, and the average gross cost of solar panels before tax credits is $16,800. Using the U.S, the average for system size at 5 kW (5000 watts), solar panel cost will range from $10,045 to $13,475 (after tax credits).


The Cost of Wind Energy in the U.S.

Wind energy is one of the most affordable forms of electricity today, with utility executives noting “Wind prices are extremely competitive right now, offering lower costs than other possible resources”.

Residential Solar and Wind Systems: What are the Costs? Wind turbine systems can run as high as $65,000 installed. The average cost nationally for a professionally installed solar panel system is about $8 to $9 per watt. A 2 kilowatt (kw) grid-tied system (no battery backup) can run to $16,000. A similar 5 kw system can cost upwards of $40,000.
