Nowadays, windmills don’t just rely on the wind’s force to push the blades into motion in order to produce energy. Modern turbines use more complicated and refined aerodynamic principles to make use of the wind’s energy most efficiently.

The two basic aerodynamic forces that work together in wind-turbine rotors are lift, which acts perpendicular to the direction of wind flow; and drag, which acts parallel to the direction of wind flow.

The blades of a turbine are shaped just like airplane wings, using an airfoil design. One surface of the blade is a little rounded, whereas the other side is quite flat.

Wind energy is one of the biggest source of renewable energy. In order to understand the working of the wind turbines, it is important to know about the different components of the wind turbine.

Although there are different types of wind turbines that operate, but the simplest possible wind-energy turbine consists of three major parts:

1. Rotor blades

The blades are the main part of the system. The blades act as barriers to the wind, although recent blade designs do more than just act as a barrier. As the wind forces the blades to move, the energy gets transferred to the rotor.

The germen manufacturing giant, Siemens, has announced that hundreds of jobs will be created through the construction of a new £80m wind turbine factory.

The offshore wind turbine production facility will be build on the east coast or in the north east of England.

According to the firm, around 700 jobs will be created with the formation of the new factory. The new turbines will be up and running by 2015, aiming to meet the increasing demand for renewable energy in the UK.

What is the purest form of power generation? The unanimous answer is Wind Energy. As Wind Energy has numerous benefits like no pollution, no burning of fossils and a clean setup. Although, it should not be perceived that it’s a facile setup unit. Various factors combine to make an impact on the amount of energy you can generate out of wind.

Power in the Wind

It’s vital to understand the relation of wind speed data with power production. Therefore, the power is proportional to the wind speed cubed. It is important to know the wind speed precisely, because any error is magnified when calculating power.

Renewable energy that is the hottest of the focal point in current times cannot be used up and it does not generate pollution. Sustainability means that we make sure we meet our energy needs and ensure the health of the planet for future generations. Eventually, we will run out of nonrenewable energy supplies and the pollution caused by using these energy sources is already becoming a serious problem. The sooner we switch to using renewable energy, the cleaner the air we breathe and water we drink will be. Among these renewable energy resources the foldable wind generator is also one of the innovations but there is still a question mark on its development.

Eolic design has been introduced in foldable wind generator class but it is uncertain as to whether it’s capable or not. The Eolic looks great and is an incredible idea, but can it actually create enough energy to power anything and is it durable enough to actually hold its ground in a wind strong enough to create electricity? Still it’s an ambitious idea and we have to sit back and see its viability.

Tidal energy is used to generate electricity through the use of tidal energy generators. By placing large underwater turbines in areas with high tidal movements, they are used to capture the kinetic motion of the ebbing and surging of ocean tides in order to generate electricity.

Tidal power is a great source of renewable energy, offering great potential for future power and electricity generation due to the massive size of the oceans.

Advantages of Tidal Energy

• Apart from the initial installation cost, tidal power is free.
• Tidal energy produces no greenhouse gases or any other kind of pollution.
• It requires no fuel.
• Electricity is produced reliably.

Tidal energy is a great source of clean renewable energy, but most of us don’t know about how it works? Every day, the tide moves a huge amount of water twice, and harnessing it could provide a great deal of energy, which can make up around 20% of Britain’s needs.

The energy generated through this process is reliable and plentiful, but converting it into useful electrical power is not easy. Some time back, “tidal power” meant “tidal barrage”,but nowadays there are other options as well.

The working of a tidal barrage is similar to a hydro-electric scheme, except that the dam is much bigger. A huge dam called a “barrage”, is built across a river estuary. When the tide goes in and out, the water flows through tunnels in the dam.

Having dished out plenty of solar power info, I got to think whether or not the majority of people are even unaware of the brains behind the project, the Solar Panel? Whatever the metaphor, lets familiarize us with the photovoltaic physical workings of this super hero enigma.

How They Do And What They Do?

As mentioned, the principles of photovoltaic physics are used to convert the energy of the sun in to electricity rather than just heat. Now the impressive scientific stuff has been duly noted, let me paint a much simpler picture.

Solar cells are not made using pure silicon but instead have impurities added to it. Why? Because pure silicon crystals are non reactive in a stable state, which is not good as the electrons need some form of instability to be productive. So in this context some impurities must be required.

Today we normally see small wind turbines right outside homes, businesses and schools. And now latest, most advanced wind turbine – not like those in our area -makes its debut in Idaho Falls.

This new wind energy system is named Blackhawk TR-10 Vault. On Wednesday morning, it started working outside the Center for Advanced Energy Studies.

ESolar launched the first commercial solar power tower in the United States, near Lancaster, California.  The Sierra SunTower solar power plant is located about 50 miles north of Los Angeles in California’s Antelope Valley.

It uses advanced computer software to precisely align thousands of flat mirrors, in order to concentrate the sun’s heat on a receiver mounted at the top of a tower.

We all know that electricity flows in wires and lights up bulbs, allowing us to use electrical devices like computers and kitchen machines. But the question arises where does the electricity comes from. In this post we will learn about how electricity is generated in power plant and in future posts we will get more knowledge of resources that produce heat to create electricity.  In next post we will get to know how electricity is brought to homes, schools and market from power plant.

How is Electricity Produced?

Thermal power plants have big boilers in which a fuel is burnt to produce heat. It is the same as a kettle on stove. When the water in a kettle boils, it produces steam that evolves through a hole above on the spout. The evolving steam makes a whistle to alert that the water is boiled.
