"Large surplus of waste corn" - Biomass
It depends on where the community is situated on our planet. In many places around the equator (and plenty beyond), the energy of the sun is abundant enough to power a society. The initial cost is great, of course, but at least this is a long-term solution instead of burning precious fossil fuels which should be turned into useful plastics instead of CO2 pollution. But that is the problem with all durable solutions to our energy needs. In places where the sun's presence isn't enough to power communities, wind, water and geothermal energy are good alternatives to conventional use of fossil fuels. Burning waste is also an option, but recycling should come first and burning waste isn't really a 'green' solution, as it still produces a lot of pollution and generally still takes fossil fuels to produce the heat necessary to destroy our waste. Advances in technology have and will continue to make ecosystem-friendly and durable solutions to our energy needs more attractive. It will be only a matter of time before oil and other fossil fuels become to scarce or it is financially more attractive to go green. Not relying on short-term solutions and investing in a durable future is good economics.
"economical" has no comparative or superlative form. You would say "more economical" or "most economical."

because...
The development of a new energy source reduces production costs for a company.
Growth depends on the volume of investment. Investment depends on capital availability. Capital may come from either internal or external source. External source of capital is costly where as internal generation of funds is economical. Generation of internal capital depends on profit making capacity of a firm. Hence, profit maximization would automatically lead to growth maximization

it is economical as you would have an unlimited source so their would need no large price raises over lack of material
It is economical to consider installing solar panels because we need the energy for our planet. The sun provides it all and solar panels would save energy and money.
Radiant energy is the safest energy for people and the environment.
describe how a alternative energy source works
would coal be a good alternative energy source for louisiana
the main source would be electric
lower activation energy, make the reaction more economical
You would eat the chicken because it uses up energy and does n't transmit much energy into the chiken egg- so it is the most economical way :)
That would depend on the sort of lamp it is. If it was a gas lamp it would be chemical energy If it was an electric lamp it would be electrical energy However you should understand that on Earth 99.9 % of the energy comes originally from the Sun. The Sun's energy is the ultimate source of stored chemical energy and the ultimate source of the electrical energy we use.
