Two Alternative & Renewable Energy Sources

by

As the world consumes and produces more energy we must cut back our us fossil fuels, and begin using alternative energy to reduce our reliance on fossil fuels

Currently we have 4 sources of renewable and alternative energy that we are able to produce: wind generation, solar energy, hydro power, and geothermal energy. Here we will discuss the most common two.

Wind Power

Wind as a source of power has been around for ages. Previous generations used wind in many different ways like, pump water, sailing ships, flour mils, saw mills and more. but at the start of the industrial and economic revolution, wind mills have improved and wind turbines were developed to supply electricity.

Lots of us learned about the old windmills in The Netherlands which were used to pump water or mill grain. The technology has improved developed hugely since the past decade. In this day and age wind turbines manage to generate thousands of megawatts of power, and once used on small scale projects, wind generation to create power will substitute standard energy sources, contributing to many households to get off the grid.

Solar Energy

Solar is the one of the most abundant form of energy available, we really should harness this great energy resource. We can use it on a large scale or a small scale. Technology is constantly improving and becoming more affordable. Households have many choices in regards Solar Energy. It can generate electricity, heat, be used for cooking etc.

Both electricity and heating systems powered by the sun are cost-effective, great for the environment and planet. Solar Installations require hardly any maintenance and after the initial investment have no running cost saving you on bills. Solar cookers are a great way of cooking food. They are affordable, portable and easy to use. It is a great solution used in many African countries where one has no power available.

Wind power or wind energy is getting more popular as an renewable energy as an alternative to fossil fuel and one of the best known of the renewable energy sources. Wind Power has been in use for hundred of years to power the wind mills in Holland and to power the sailing boats of yesteryear. To generate electricity through the use of wind power requires wind turbines. Wind turbine generators do little to harm the environment and are clean and preferable source of energy compared to fossil fuels. The only disadvantage of wind power is that wind power cannot be used everywhere. To make effective use of wind power and use turbines to generate wind power you would need an average wind speed of at least 21 kilometers per hour. Obviously those wind speeds are not found everywhere. You will find that most large scale wind power farms can be found near coastal areas.

Wind Power in South Africa

There are currently no large scale wind farms operational in South Africa, though a number of wind farms are in the initial planning stages. Most of these wind power farms are earmarked for locations along the windy Eastern Cape coastline. Eskom has constructed one small scale prototype wind farm at Klipheuwel in the Western Cape and another demonstrator site is near Darling with phase 1 completed.

Wind Power the future of renewable energy

Wind is a sustainable fuel source free of pollutants of any kind and its free energy can be harnessed without causing any damage to the environment. The energy used to manufacture and erect a wind turbine is recovered in the first 3 to 6 months of operation. At the end of a wind turbine’s lifetime, typically 30+ years, it can be removed, leaving behind no lasting legacy.

Cost effectiveness of wind power

Although the initial investment in a wind power farm is higher than a traditional fossil powered system, with no ongoing fuel cost the price of generating electricity works out cheaper over the lifetime of the investment with the added benefit of being kinder to the environment.
