"Biofuels" are transportation fuels like ethanol and biodiesel that are made from biomass materials.

Ethanol and biodiesel are usually more expensive than the fossil fuels that they replace, but they are also cleaner-burning fuels, producing fewer air pollutants.

What Is Ethanol? Ethanol is an alcohol fuel made from the sugars found in grains, such as:

Unlike gasoline, pure ethanol is nontoxic and biodegradable; it quickly breaks down into harmless substances if spilled.

Cancel
Ethanol and ethanol-gasoline mixtures burn cleaner and have higher octane than pure gasoline, but have higher "evaporative emissions" from fuel tanks and dispensing equipment. These evaporative emissions contribute to the formation of harmful, ground-level ozone and smog.

Cancel
Ethanol may be considered to be carbon-neutral because the plants that are used to make fuel ethanol (such as corn and sugarcane) absorb CO2 as they grow and may offset the CO2 produced when ethanol is made and burned.

Fueling engines with biodiesel has just started to catch on, but it isn't a new idea. Before petroleum diesel fuel became popular, Rudolf Diesel, the inventor of the diesel engine in 1897, experimented with using vegetable oil (biodiesel) as fuel.

Using a gallon of biodiesel produced in the United States avoids the CO2 emissions that result from burning about a gallon of petroleum diesel. Biodiesel may be considered to be carbon-neutral because the plants that are used to make it, such as soy beans and palm oil trees, absorb carbon dioxide (CO2) as they grow and may offset the CO2 produced when biodiesel is made and burned.

Biodiesel is a renewable fuel that can be used instead of diesel fuel, which is made from petroleum. Biodiesel can be made from vegetable oils, animal fats, or greases. Most biodiesel today is made from soybean oil. About half of biodiesel producers are able to make biodiesel from used oils or fats, including recycled restaurant grease.

wind farms are not only capital intensive but also have a long gestation period – could prove to be prohibitive for many potential investors.

terms of global policy, governments need to boost investments in onshore and offshore wind generation through the right mix of supportive policies and incentives.

wind energy will become even more attractive as it serves as an insurance against future increases in fuel and carbon prices, while reducing our dependency on fossil fuels imported from volatile regions.

Both in Europe and in the US, some 40% of all new power generating capacity installed in the past two years was wind energy. If the economic crisis continues, however, the reduction in power demand will start to impact wind energy, simply because of lower demand for new power plants. Nevertheless, the medium and long-term outlook remains very healthy, as political momentum is building towards a low carbon economy, without which humankind will not overcome three of the biggest concerns of our time – climate protection, energy security and the provision of jobs.

Wind power’s credentials as a rapidly deployable clean technology have put it at the forefront in the fight against climate change. Neither new nuclear capacity or carbon capture and storage (CCS) will contribute to CO2 reductions within the timeframe that the climate scientists give us. As a no-fuel, no-carbon emissions source of electricity, wind energy will play a big part in reducing carbon emissions before 2020.

The growth in wind power capacity has shown no signs of slowing, even in these tough economic times. For two years running there has been more new wind power capacity installed than any other power generating technology in Europe – including coal, gas and nuclear.

Wind power is a leader now, and will remain so in the future, attracting big investments and creating jobs. There is a boom waiting to happen in offshore wind energy. But, Europe’s ageing electricity grids must be upgraded and extended, and the EU must also pursue a drive to build an offshore grid in the North and Baltic seas that will connect offshore wind farms to the shore, piping vast amounts of CO2-free energy to consumers at affordable prices.
