Renewable Energy Resources Wind Turbines Vs Solar Panels...

RENEWABLE ENERGY RESOURCES - WIND TURBINES VS SOLAR PANELS – HOW THEY WORK Wind turbines: A wind turbine turns wind into energy. As wind blows towards the blades of the turbine, the rotors spin around, capturing kinetic energy from the wind. The rotor blades are able to rotate around the hub (located at the front, middle of the turbine) allowing them to meet the wind at the best possible angle. Inside the nacelle (the main body of the turbine), the gearbox is able to convert the low-speed turning of the drive shaft into high-speed rotations that are fast enough to drive the generator proficiently. The generator then takes the kinetic energy from the spinning shaft and turns it into the electrical energy. With the help of anemometers that provide the measurements of wind direction and speed, the rotors and nacelle can be rotated by a yaw motor allowing the blades to face directly towards the oncoming wind, capturing the maximum amount of energy possible. The electrical current produced by the generator then flows through a cable running through the centre of the turbine to wer. From there, a step-up transformer converts the electrical energy to a voltage about 50 times higher. The energy can then be transmitted efficiently to buildings and homes nearby or to the power grid. Solar Panels: A solar panel turns the sun’s light into energy. Solar panels are made up of many small solar cells. Every one of these cells needs light from the sun to allow the electrons to move.

Should Replace Fossil Fuel With Renewable Energy994 Words   |  4 PagesGomez Professor Melissa Tran English 061 26754 14 November 2016 Renewable Energy The U.S. should replace fossil fuel with renewable energy. There are many reasons that the U.S. can use renewable energy to improve the economy. First of all, renewable energy can have a more stable price. Unlike fossil fuel, renewable energy is a continual source of energy that will not be as demanded, and will not cause inflation. Next, using renewable energy is a key to having a clean and green environment. It will notRead MoreRenewable Energy: Is It the Solution?1571 Words   |  7 PagesIntroduction Renewable energy is considered a revolutionary thing, something that can save us from peak oil and climate change, but is it really what it seems? Renewable energy can help ease our predicament. There are multiple ways to achieve this, including the use of newer, greener technologies such as wind, solar power, and biomass.
