Wind Turbines (Onshore)

Electricity Generation

Proliferation of turbines, dropping costs, and heightened performance mean onshore wind farms are at the forefront of initiatives to address global warming.

Wind Turbines (Onshore)

Reduced CO2: 85 gigatons
Net cost (Billions US$): $1,225.37
Net operational savings: $7,425.00 billion
What do these numbers mean?

TOTAL CO2-EQ REDUCTION (GT)

Total CO2-equivalent reduction in atmospheric greenhouse gases by 2050 (gigatons)

NET COST (billions US $)

Net cost to implement

SAVINGS (billions US $)

Net savings by 2050

Impact:

An increase in onshore wind from 3 to 4 percent of world electricity use to 21.6 percent by 2050 could reduce emissions by 84.6 gigatons of carbon dioxide. At a cost of $1.23 trillion, wind turbines can deliver net savings of $7.4 trillion over three decades of operation. These are conservative estimates, however. Costs are falling annually and new technological improvements are already being installed, increasing capacity to generate more electricity at the same or lower cost.

Tree Intercropping

Food

Like all regenerative land-use practices, tree intercropping — intermingling trees and crops — increases the carbon content of the soil and productivity of the land.

Tree Intercropping

Reduced CO2: 17 gigatons
Net cost (Billions US$): $146.99
Net operational savings: $22.10 billion
What do these numbers mean?

TOTAL CO2-EQ REDUCTION (GT)

Total CO2-equivalent reduction in atmospheric greenhouse gases by 2050 (gigatons)

NET COST (billions US $)

Net cost to implement

SAVINGS (billions US $)

Net savings by 2050

Impact:

Accounting for different sequestration rates across regions and intercropping systems, we estimate total sequestration of 17.2 gigatons of carbon dioxide over thirty years. To achieve that impact, adoption of tree intercropping would need to grow to 571 million acres globally. On an additional investment of $147 billion, savings could be $22 billion over three decades.
