Energy history facts

From ancient times people use various energy sources. Geothermal energy were used for springs and heating, hydro and wind energy were used for mills, sailing, water pumps and other mechanical devices, solar energy was used for heating, biomass and coal were used for heating, illumination, cooking, and so on.  For example, nearly 2000 years ago the Greeks used water wheels to grind wheat into

Solar and wind – Current status facts

Solar energy is almost limitless source of renewable energy in our planet. The scientists have calculated that the total amount of solar energy absorbed by our planet is approximately 3,850,000 exajoules (EJ) per year. What this means is that solar energy really has enormous potential, and that covering only 4% of the world's deserts with solar panels would be enough to satisfy all of the

How to build wind turbine blades at home?

Large wind farms are being installed in many parts of the world but the popularity of small wind turbines among homeowners and commercial businesses is also rapidly growing as small wind turbines are now being increasingly used to supplement energy consumption and also serve as an alternative mean to help our environment from pollution caused by fossil fuels.

If we look at the current numbers

Wind energy industry - current trend facts

Wind energy industry has been rapidly developing in the last few decades. One of the main reasons for this is that wind energy has many advantages such as no pollution, no carbon dioxide emissions (CO2), relatively low upfront costs and long history of use. Wind turbines have been used for more than a century, and the real breakthrough in wind power technologies occurred in the 1940s with the

Wind power jobs facts

The wind industry employs professional and skilled workers in a number of different capacities. New wind projects require people with meteorological, business, and engineering experience to plan and build wind energy projects. Meteorologists help engineers to identify appropriate sites with a suitable wind conditions. After that engineers design the wind farm, working with the utility companies

Clean energy race - China plays to win

Renewable energy jobs can give significant boost to any economy, including US economy, but China is the one that is getting the lion's share out of it. If we look at the current numbers we can see that China has more than million people working in its renewable energy industry. If we translate this into the production number it means that China produces half of the world's wind turbines, supplies

Is wind power efficient enough?

Is wind power an economically and ecologically acceptable alternative to cheap fossil fuels such as coal? According to some latest reports relying on windmills to reduce greenhouse gas emissions is not only an expensive energy options but is also doing significant damage to the environment. A recent Wall Street Journal column by Robert Bryce says that wind energy will not help to reduce carbon

U.S. wind energy industry needs help from Congress

U.S. wind power capacity experienced growth of 39 percent last year but was not followed with green job growth as uncertainty about renewable energy policies and the global recession slowed overall production.The total installed capacity of new U.S. wind turbines accounted for more than 9,900 megawatts, which despite the recession is still the significant increase compared to 8,400 MW in the

Wind energy sector - Wind energy development

Wind energy isn't something brand new, and as many of you probably know that wind energy use (windmills) has very long history of using it. If we look at the data for United States in 2008 we can see that twenty-two states have come up with the plans for the installation of 1650 windmills in the United States. Current estimates say how by 2014, wind power industry expected to rapidly increase its

North America - 40,000 new wind turbines by 2015

North America, particularly U.S. desperately needs much stronger renewable energy sector, and the most promising look to be solar energy and wind energy. The latter one could looks to be soon experiencing new boom with the deployment of 40,000 new wind turbines across North America, and in the period of only 6 years, by the year 2015. Well, this is at least what report from Pike Research has to

Are wind farms a threat to birds?

Many environmentalists believe that wind turbines drive birds away from surrounding areas but the latest study carried out by British researchers said the opposite giving the green light to build more wind farms. The concept of this theory was that large birds could get caught in the turbines which would kill them, and also that the structures could disturb other species in nearby area.However
