Alternative energy
Non-fossil energy sources that have no negative effect on the environment
Mostly renewable

Biofuels
Fuel obtained directly or indirectly from biological processes
Renewable if from plants or microalgae biomass obtained using natural resources e.g. sunlight Additional benefit of carbon

Challenges to sustainable production of microalgal biofuels
No one has been able to produce enough microalgae biomass using sunlight at low-cost Inefficient sunlight energy conversion Low productivity High capital cost
Cost of biofuels is high Estimated biodiesel cost is $1.6 - >$75/L
