Importance of Renewable Energy and Types of Renewable Energy Resources

Today, the majority of the world is currently dependent on various sources of fossil fuel, such as coal, gas, or oil. These resources are finite in nature, and the process of unearthing and using them is very damaging to the environment as a whole. Renewable energy is energy taken from sources which don’t run out, such as the sun, the wind, and the sea. Though we are still at the beginning of our journey into how to use renewable energy, we have already made huge strides in harnessing it.

One way we have moved forward in harnessing renewable energy is by the use of feedback actuators, or linear actuators, in our set ups. Solar panels in particular have benefitted from this, as they have been able to pick up much more energy than they could before. Linear actuators have made solar panels much more moveable, so they can follow the sun as it moves, to pick up every last bit of sunlight that they can.

Solar Panels

Solar panels are perhaps the most easily-recognizable form of renewable energy for most people, since they are now quite common in people’s houses. Solar panels are designed to pick up and store the heat and light of the sun, and use it for various energy purposes in homes and businesses. As a result, more and more homes have solar panels incorporated into their roofs, to give them the best chance of catching the sun.

Solar panels are the most likely to have linear actuators involved, since they rely most heavily on linear motion to be able to do their job properly. Having linear actuators means that solar panels can smoothly follow the sun as it moves along its path, allowing them to collect more energy than they otherwise would have.

Wind Farms

Wind farms are the best way to collect wind power, and more and more people are finding that either they live near a wind farm, or that they can erect a miniature turbine of their own to use for their own property.

Wind turbines work on essentially the same principle as windmills do; they have huge propeller-like tops, which are pushed round by the wind as it blows. When this happens, the energy which is produced by the turbines turning is sent down the shaft of the turbine to be stored as electricity until it is needed.

Wave Power

There are a number of different ways of capturing and storing wave power, including dams and booms. These work by acting as a barrier which creates energy from the ebb and flow of tides. A dam works by keeping all the water in a tight space, allowing for the movement of the water to be controlled to a far greater extent than would otherwise be possible. Being kept in a confined space makes the water more powerful, which results in more energy to be collected.

Booms do not use the confinement of water as a way of gathering electricity, but instead rely on its normal activities to gather electricity. Booms lie on top of the water, normally quite near the shore, and as the waves go under them, they can gather up energy from them and send it inland to be stored as electricity.
