And if alga is going to become a commercially
viable fuel source, scientists must ensure that not only can it produce as much oil as possible, but also that it can grow as fast as possible.
Not exact matches
And it could mean a future
viable source of energy that emits no pollution or radioactivity, burns no fossil
fuels, and could be no more expensive to run than conventional coal or electric power plants.
The experiment has potential as a
source of renewable

I doubt that politicians truely understand the problem at hand, it is not as if we have a new energy technology ready to fill in for fossil fusl at the present time and whilst I am sure than energy efficiency can reduce carbon emissions by around 25 % it will be left to the markets to decide this and that means awaiting the onset of peak fossil
fuels to push up the price of it that will make other energy
sources more
viable.

So it appears to me that we are left with the choice between two «imperfect» solutions: one that faces immense political opposition today and the other that «buys us the time» to develop a «more perfect» solution: i.e. a technically and economically
viable alternate energy
source, which does not depend on fossil
fuels.
The study pins great hopes on the ability of carbon capture and sequestration (CCS) to reconcile coal's importance as an energy

fuel emissions.
But it offers no

fuels.
When the fossil
fuel sources of these environmental impacts are made to pay the true cost of the pollution created, through mandated updated technological fixes such as improved and more efficient pollution control, limited coal

Public officials responsible for decisions made by Health Canada continue to espouse the now worn phrase: «This
source of energy is viewed as a
