Taller wind turbine towers can generate more wind power

E-mail Print PDF

The future of wind energy is often said to be offshore because of more powerful and more consisted winds compared to those on land. But there is also one solution to generate more wind energy from wind farms on land, in form of taller wind turbine towers.

The current height standard for wind turbines is 80 meters (about 262 feet) from the ground.  However, if developers were to build higher projects it would generate more wind power and wind farms could expand into new areas and new states.

One interesting study from the Iowa University claims that the taller towers (of up to 140 meters) could enable wind energy production in all 50 U.S. states.  Winds at higher elevations, generally speaking, are considerably stronger and more consistent, even in wind-rich states such as Iowa and Texas.

Dutch make big steps in offshore wind development

E-mail Print PDF

One of the largest offshore wind energy projects in the world, the Gemini offshore wind farm , is now officially opened. This 600 MW facility located 85 kilometres north of the Groningen coast, has put Netherlands among the leaders in global offshore wind development.

Once fully operational, this offshore wind farm should provide enough power to supply 785,000 Dutch households with clean, renewable energy. This $3 billion project is a joint project that includes the Canadian independent renewable energy company Northland Power, wind turbine manufacturer Siemens Wind Power, Dutch maritime contractor Van Oord and waste processing company HVC.

Gemini should provide around 13 percent of the country's total renewable energy supply, and about one quarter of its total wind power.

How to Understand Your Electric and Gas Bills

E-mail Print PDF

When you get your electric and gas bills in the mail every month, you probably don't take too much time to read through your consumption rates. Since it's all written in the dense, technical language of energy scientists, it doesn't exactly make for easy reading.

However, what few people realize is that the bill itself offers quite a few avenues for increasing energy efficiency. While gas is typically easy enough to manage, electricity can be somewhat trickier. To reduce your electric bill, you need the advice of an expert in home and commercial electricity.

Nevertheless, there are surprising benefits to be had by paying attention to your consumption as stated on your monthly bills.

The secret behind the rapid growth of wind power capacity in United States

E-mail Print PDF

In 2016, wind power managed to surpass hydropower thus becoming the largest source of renewable electricity in United States.  It is now the fourth-biggest source of electricity behind natural gas, coal, and nuclear energy.

The majority of energy analysts agree that wind power capacity will continue to rise significantly in years to come. But what has made wind energy such a renewable energy force in United States?

The answer to this question lies in costs and technology.  The technological advancement in wind energy technologies did not only improve wind turbine efficiency, it has also contributed to significant decline in wind energy costs.

Popularity of heat pumps increases

E-mail Print PDF

The prices of traditional types of thermal service regularly increase. The fact that they do harm to the environment has to be reconsidered. Changes gradually happen, and now the whole world watches renewable energy sources. In a race of alternative energy sources, the thermal pump has proved the efficiency as the eco-friendly option of usual house heating. However, thermal pumps can differ according to characteristics.

The pumps are capable of absorbing thermal energy from the air, even at rather low subzero temperatures.

Depending on features of the construction, heat pumps are divided into two types:

  • Air-to-water pumps in heating contour of which the liquid circulates,
  • Air-to-air when the house is warmed up with air.
