An 80% reduction in US greenhouse gas (GHG) emissions by 2050 has been generally established as the de facto required domestic contribution to stabilizing global concentrations at low to medium levels, that is, 450 and 550 ppm carbon dioxide equivalent (CO 2 -equiv). They considered three levels of GHG-intensity for US electricity supply.

Climate pledges by governments to date—even if fully achieved—would fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C, Solar is the world’s single largest source of total energy supply.

Additionally, few of current harvesting and dewatering technologies available today are amenable to scaling for larger production scenarios of 1,000 acre or larger algal farms. Algae cultures tend to be relatively dilute, and the energy requirement to remove water from the cultures can be a significant portion of the energy balance.

A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. A TWP >1 means that the cumulative radiative forcing from choosing natural gas today is higher than a current fuel option after t yr.

The combination of harvesting whole forests and burning long-sequestered carbon sources such as coal or oil has impaired the Earth’s carbon cycle at an increasing pace. To restore balance we must protect the oxygen-producing biomass of Earth and reduce the amount of carbon emissions.
