"Energy [R]evolution: A Sustainable World Energy Outlook", 2010
Scenario by Greenpeace and EREC provides a detailed practical blueprint for cutting carbon emissions while achieving economic growth by replacing fossil fuels with renewable energy and energy efficiency.
Global CO2 emissions under the Energy [R]evolution scenario would peak in 2015 and drop afterwards. Compared with 1990 CO2 emissions will be more than 80% lower by 2050 if the energy supply is based almost entirely on renewable energies. By 2050 around 95% of electricity could be produced by renewable energy.

WHY RENEWABLES ARE IMPORTANT
Fossil fuels (oil, coal, and natural gas) currently provide about 85% of all the energy use in the US. These resources are being constantly depleted and can't be replaced within any practical time span. How long exactly would these resources last? The remaining amount of a particular resource is often characterized by so-called Reserves-to-Production ratio (R/P).
In a plain language, R/P basically gives us the length of time the reserves would last if its usage continues at the current rate. Here are estimated world total reserves-to-production ratios for the main conventional fuels: oil - 45 years, natural gas - 62 years, coal – 119 years.
Aside from being finite, energy production from fossil fuels results in by-products of combustion, or emissions. These emissions affect the environment and may be causing the climate change. In contrast, renewable energy (RE) resources, as the name implies, are constantly replenished naturally and will never be exhausted. Their use generally has a much lower environmental impact than that of conventional fuels, which is why the technologies that utilize them are often called "green". In addition, RE can boost US energy security by reducing our dependence on the imports. All these factors, coupled with the government incentives and mandates, result in growing public interest in using renewable sources of energy. While many green technologies are large-scale, most of them are also suited to private homes, especially in rural areas. This website provides quick reference information for using alternative power at home.
What is CONCERTO?
“The CONCERTO initiative, launched by the European Commission , is a Europe wide initiative proactively addressing the challenges of creating a more sustainable future for Europe’s energy needs. Today, there are a total of 58 communities in 22 projects, each working to deliver the highest possible level of self-supply of energy. CONCERTO is part of the framework research programme supervised by the DG Energy and Transport of the European Commission.
CONCERTO IN A NUTSHELL
CONCERTO supports local communities, as clearly defined geographical areas or zones, in developing and demonstrating concrete strategies and actions that are both sustainable and highly energy efficient. Interactions and relevant energy flows between centralised and decentralised energy supplies and demands can be identified, measured and assessed.
The CONCERTO initiative has been only possible as a result of the strong commitment from the relevant, local authorities and includes technical experts, academics, and private companies from across Europe.
6th Asia Clean Energy Forum 2011: New Business Models and Policy Drivers-- Building the Low-Carbon Future
ADB Headquarters, Manila, Philippines: 20-24 June 2011
According to reports from the World Bank on 28 May 2009, USD 600 million of financing has been approved for Turkey’s Private Sector Renewable Energy and Energy Efficiency Project.
The report stated that Turkey’s rapid economic growth in recent years has caused increasing demand for electricity, yet the real challenge is ensuring Turkey’s energy security and at the same time reducing greenhouse emissions that induce climate change.
The main objective of this project is to increase the efficiency and production capacity of electricity generating plants in the private sector, which will result in the reduction of greenhouse gas emissions.
Moreover, key measures in the project include tapping into Turkey’s significant potential in renewable energy such as wind, solar, biomass and geothermal and ensuring a more efficient use of energy to reduce waste in energy consumption.
National and international wind energy industries and wind power technologies shall meet under a specialized exhibition, WindTech Istanbul, between the dates of 13-16 October 2010 in Istanbul for the first time in Turkey. WindTech is an exhibition, which targets the wind energy sector and which meets this sector under single roof.
WindTech Istanbul Wind Energy Trade Fair will take place in Istanbul Lutfi Kirdar Convention and Exhibition Centre (ICEC).
Objectives of WindTech Istanbul:
- To prepare a foundation for the creation of wind energy industry, to develop it and to provide contribution for it,
- Meeting of the Turkish investors with the equipment suppliers,
- To meet the foreigner investor with the Turkish producer in Turkey, where it is a great potential in the field of energy in terms of the investment and the production,
- To emphasize the fact that Turkey should search for its energy needs on the alternative sources and should direct itself towards renewable sources,
- To support the domestic industry and the production of turbines,
- To introduce the fields of use of wind energy,
- To create a platform for projects, which would increase the industrial efficiency,
- To show the importance of the need to go for variation for the energy supply and of the vitality of evaluation of our national energy sources and to underline that these are priority issues, (Minister of Energy and Natural Sources, Mr. Yildiz, has stated that, “we require to meet 30% of our total energy port folio from these sources, together with renewable energy sources and natural sources until 2030.This is a number, which is even above the EU average”)
- To play a triggering role for the start of the investment projects, which will be carried out in this filed, after the Draft Law with regards to make changes in the law, which is related to the Use of Renewable Energy Sources with regards to the Production of the Electrical Energy,
- To create a environment for the implementation of the investments, which will provide for the implementation of the investments that would be required and would be sufficient with regards to the security of the supply,
- To underline for the fact that the wind energy, which is the environment friendly, with minimum amount of carbon gas discharge, clean and widely available, form of energy due to the sanctions of the agreements like the Kyoto Protocol, etc, in order to have preventive measures for important issues like, global warming, change of the climate,
- To achieve the target, where it is thought that Turkey might have 20.000 megawatt of wind power by 2020.
Biodiesel Burns Significantly Cleaner than Diesel
Biodiesel is renewable, nontoxic, and biodegradable. Compared to diesel, biodiesel burns significantly cleaner. It produces fewer air pollutants like particulates, carbon monoxide, hydrocarbons, and air toxics. However, it does slightly increase emissions of nitrogen oxides.
A Fuel That Smells Like French Fries
Biodiesel produces less black smoke than regular diesel, and it smells better, too. Sometimes biodiesel exhaust smells like french fries!
A Fuel With No Sulfur
Regular diesel fuel contains sulfur. Sulfur can cause damage to the environment when it is burned in fuels. The amount of sulfur in diesel fuel is regulated by the Federal government.
When sulfur is removed from regular diesel fuel, the fuel doesn't work as well. Adding a small amount of biodiesel can fix the problem. Biodiesel has no sulfur, so it can reduce sulfur levels in the Nation's diesel fuel supply while making engines run smoother.
"Biofuels" are transportation fuels like ethanol and biodiesel that are made from biomass materials. These fuels are usually blended with the petroleum fuels — gasoline and diesel fuel, but they can also be used on their own. Using ethanol or biodiesel means we don't burn quite as much fossil fuel. 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:
Other sources of sugars to produce ethanol include:
- Potato skins
- Sugar cane
- Sugar beets
- Yard clippings
Most of the ethanol used in the United States today is distilled from corn. Scientists are working on cheaper ways to make ethanol by using all parts of plants and trees rather than just the grain. Farmers are experimenting with "woody crops," mostly small poplar trees and switchgrass, to see if they can be grown cheaply and abundantly.
Ethanol Is Blended With Gasoline
About 99% of the ethanol produced in the United States is used to make "E10" or "gasohol," a mixture of 10% ethanol and 90% gasoline. Any gasoline powered engine can use E10, but only specially made vehicles can run on E85, a fuel that is 85% ethanol and 15% gasoline.
What Is Biodiesel?
Biodiesel is a fuel made from vegetable oils, fats, or greases — such as recycled restaurant grease. Biodiesel fuel can be used in diesel engines without changing them. It is the fastest growing alternative fuel in the United States. Biodiesel, a renewable fuel, is safe, biodegradable, and produces lower levels of most air pollutants than petroleum-based products.
