Our current energy situation will not be solved with one, cure-all solution. It will require a broad
collection of sustainable and economical technologies. There are many proven options for renewable energy and
biofuel technologies on the market today as outlined below.
Renewable Energy sources are characterized by high sustainability, low feedstock costs and minimal
emissions in the following forms:
Electricity or fuel can be produced through the direct incineration or gasification of Municipal Solid
Waste (MSW) from waste-water treatment plants or industrial, commercial, and household garbage.
Waste-to-energy provides clean, renewable energy for a variety of users and eases the burden MSW
places on landfills.
- Landfill Gas
Methane produced by the decomposition of waste is a highly polluting green house gas. Landfill gas
operations capture methane and refine it to use in place of natural gas for electricity generation,
vehicle fuel and heating.
Photovoltaics produce electricity directly from sunlight and can be integrated into any building
or utility system. Solar power can be harnessed anywhere from a rooftop installation to an expansive
solar farm covering acres of land. Recent innovations in thin film technology make it possible to
convert any surface into a clean, renewable power generator.
Wind power is generated with the use of turbines. Modern turbines are available in a myriad of
shapes, sizes and power generation capabilities based upon the available wind potential and the
desired end use such as residential, commercial or large utility scale wind-farms.
In areas of geothermal activity, conventional steam turbines are used to generate electricity. Rather
than burn fossil fuels to produce steam, geothermal uses the latent heat of the Earth’s core.
Biofuels recycle existing carbon based feedstock into clean fuel in the following forms:
Biogas is produced by the anaerobic decomposition of various materials such as biomass, manure,
sewage, municipal waste or energy crops. With proper treatment, it can provide a clean burning,
renewable replacement to natural gas.
Natural oils and fats are converted into biodiesel which is a cleaner burning alternative to
petroleum diesel. Jatropha, palm and soy-bean oils and most waste oils and fats such as
rancid cooking oil, trap grease, lard, and tallow, which present a disposal hazard, can be
converted to useful fuel.
Waste cellulosic sources such as wood chips, plant and lawn clippings, organic municipal
waste or purpose grown, high biomass yielding, plants like switchgrass and sugar cane can
to be converted to ethanol. Ethanol can then be used in gasoline or flex-fuel engines as
a cleaner alternative to oil-based gasoline.
Algae convert atmospheric carbon-dioxide into oils that are collected and converted into
biodiesel and other various biofuels. Algae can also be used to clean up industrial emissions,
thereby protecting the environment.
