Fears that increased energy demand, as well as the need for ecologically acceptable fuels that would replace highly polluting fossil fuels are the main reasons behind many different alternative energy researches. One segment of the alternative fuel market that has been recently gaining plenty of popularity are biofuels. The definition for biofuels is any liquid fuel that originates from renewable plant materials. When we compare biofuels with the gasoline we can see that the gasoline is refined from limited crude oil supplies, while biofuel can be produced from a number of organic sources that are not limited like oil is. According to some energy experts, biofuels are the only renewable energy sector that is capable to replace currently dominant fossil fuels.

One of the first major discoveries in biofuel technology was developed using corn and wheat products. This created controversy amongst many different circles in the scientific as well as social community. Critics have claimed that crops used in the production of food should not be turned in to fuel because of the potential damage it could cause on the food supply and increase food prices, especially since today there are over billion hungry people in the world. Researchers have since focused more on creating biofuels deriving from plants that typically have no real value in global food supply.

India looks to be ready to launch massive "Solar Mission" under the National Action Plan on Climate Change. Under this National action plan India should install 1,000 MW of solar power every year by 2013. Leading energy experts believe that if this solar expansion goes well it could lead to massive solar power installed capacity of 20,000 MW by the year 2020. That's an ambitious goal for India, which added about 25 megawatts of generation capacity in 2008, according to GTM Research. From 2001 to 2008, the country had erected 143 megawatts of solar energy systems.

In the first phase that should happen between 2010 and 2013 India also plans to install 200 MW of off-grid solar power and cover seven million square metres with solar collectors, and by the end of the final phase in 2022, the government hopes to have 20,000 MW of grid-based solar power, 2,000 MW of off-grid solar power and cover over 20 million square metres with collectors.

In 2008, cumulative installed wind power capacity increased nearly 29% worldwide which is the highest gain of all renewable energy sectors. At the close of 2008, three-quarters of the nearly 121 GW of the world’s wind generating capacity was operating in the IEA Wind member countries. In the IEA Wind member countries, 17,000 MW was added in 2008 for a total of close to 92 GW of generating capacity. Electrical production from wind energy also heavily increased by more than 25% in IEA giving great boost to new investments and future wind projects. Located in Europe, North America, Asia, and the Pacific Region, the member countries are sharing information and research efforts to increase the contribution of wind energy to their electrical generation mix. Though this electricity production seems big it accounted only 2% of the total electrical demand in the reporting IEA Wind member countries, however this is still step ahead compared to 1.6% in 2007.

Wind energy is one of the most important renewable energy sources, and if we are to believe a European Wind Energy Agency (EWEA) wind could provide 17% of EU's electricity by 2030. This however would require a serious improvement of wind energy sector in Europe because offshore wind farms are currently meeting just 0.3% of total EU electricity demand. In order to achieve such bold targets wind energy sector must first overcome various challenges such as development of the European offshore grid, receiving lot more political support and also needs to be included in improving member states energetic plans.

EWEA report claims that existing and planned European offshore wind projects will, if implemented, supply 10% of Europe's current electricity needs; this would not only be good from energy but also from ecological point of view because over 200 million tonnes of CO₂ emissions every year would be avoided with such a percentage of wind energy in global EU energy demand.

President Obama called a House-passed energy bill "an extraordinary first step" toward tackling climate change and reducing the use of fossil fuels, but he also expressed some reservations about a bit controversial provision that intends to slap tariffs on imports from countries that do not have similar laws. Obama predicts that such measure would spark innovation and jobs, and that its costs to consumers would fall well short of critics' warnings.

According to this new bill power plants, factories and other major emitters would need to either obtain permits for their emissions or invest in "offsets," such as reforestation, that reduce the amount of carbon dioxide in the atmosphere. This energy bill also includes strict energy efficiency standards and requirements for wind, solar and other renewable electricity use. Regarding provision that aims to penalise imports from nations that fail to cut their emissions in step with the United States, Obama said how "U.S. have to be very careful about sending any protectionist signals, especially when global economy is still in deep recession."

World population is constantly growing and Europe is no exception. The bigger the population the higher energy demand there is, and Europe already tries to figure future out energy sources that could satisfy future energy demand. One of these future energy sources could easily become Africa, or to be more precise Sahara desert in North Africa.

At least this is what “Desertec”, an organization focused on sustainable energy for Europe, Asia and the Middle East says. This famous company believes that the vast Sahara Desert of North Africa is perfect for solar energy exploit, and that all there is needed are further research and of course adequate funding. In order to do so, Desertec already announced plans to raise financial means adequate for not only research but also for building infrastructure. According to their estimates such project would cost somewhere around $600 billion. Despite the high investment costs many energy experts are optimistic about this project because of its enormous potential.

UK's Department of Energy and Climate Change (DECC) has issued latest report how Britain has failed to reach its renewable energy targets. There were lots of talks in Britain about the necessity to revive renewable energy sector but in the end this hasn't resulted in anything except disappointments. The internal UK forecasts show that by 2020 the UK will be getting only 5% of its total energy from renewables, far short of the 15% target that UK signed up to with the European Commission.

This data shows that UK's government is still miles away from turning Great Britain into respectable renewable energy force. It also shows that UK must make quick changes to its energy policy because in the past decade government lacked a credible and comprehensive energy policy. Some other countries, with less available funds than Britain, are doing much bigger changes in renewable energy sector, so it is really a shame that UK still fails to follow renewable path.
