A Nation’s consumption of energy directly correlates to its economic performance. Globally, the United States is recognized as a nation with a high economic performance and the substantial consumption of energy in the United States reflects this economic factor. Energy is the largest market in the world economy and continues to grow.
United States end-use energy consumption is comprised of electricity, thermal, and transportation. End-uses for liquid fuel total approximately 41 quadrillion Btus per year. For the three end-uses of energy, liquid fuel, natural gas, coal, nuclear, and renewables provide the approximate 100 quadrillion Btus of energy consumed per year in the US.
Electric, thermal, and transportation energy use in the United States contribute 5,890 million tonnes of CO2 emissions each year. Liquid fuel and coal emit approximately 4,715 million tonnes of the 5,890 million tonnes of CO2 emissions per year.
Energy density is crucial for transportation applications – the traditional liquid fuels derived from crude oil, namely jet fuel, gasoline, and diesel, lead the list of transportation fuels
The widening gap between US oil production and US oil consumption is filled by foreign oil imports.
Oil imported from the Persian Gulf is nearly $1T per year, which translates to a cost per gallon of ~$26 to the US taxpayer.
In an effort to secure domestic sources of oil and reduce CO2 emissions, the US produces renewable fuels; of the renewable fuels, algae’s biomass productivity and infrastructure compatibility makes it the leader
Algae can enable beneficial reuse of CO2, allowing the US to utilize its vast volumes of coal for power generation and renewable transportation fuel production
Transportation fuels need to have characteristics to match upcoming policy and infrastructure.
