Top 5 renewable energy sources of near future

  1. 1. Top 5 RenewableEnergy Sources Of Near Future
  2. 2. 1. Solar: We have just started harnessing the power of Solar energy. Our efforts, technology and investments in this area are just a scratch on the surface yet. Solar power is expected to provide almost a quarter of the world’s electricity supplies by 2050, according to a new report published by the International Energy Agency (IEA). This is essential for us to cut down carbon emissions and in coming years that will be our main focus. Solar energy will provide a better alternative. Solar power currently accounts for 0.5 percent of total electricity supplies but eleven percent of total supplies are predicted to come from solar panels on homes and offices while a further 11 percent will be provided by central solar power stations feeding clean electricity to populous areas. It will get better with time. Better availability and implementation of technology will enable us to harness solar energy at all levels very soon.©
  3. 3. 2. Wind: In the near future, wind energy will be the most cost effective source of electrical power. In fact, a good case can be made for saying that it already has achieved this status. Today wind turbines are becoming more efficient and are able to produce more electricity given the same factors. Wind has jumped ahead of other green energy sources because innovations in turbine technology (think: windmills) have improved the efficiency and made systems the most cost effective alternative. Turbines can generate electricity with wind speeds starting at 8 to 16 miles per hour according to the U.S. Department of Energy. Turbines are typically built in groups on wind farms where the wind is the strongest. The largest U.S. wind farm is near Abilene, Texas, with 421 turbines scattered across 47,000 acres. United Kingdom is leading the offshore wind farms right now. Huge wind turbines with a span rivalling that of the London Eye could form part of the UK’s energy future. The first giant offshore turbine, named Britannia, will be complete by 2012. It is evident that in coming time, it will be even stronger and will emerge as the biggest practical renewal energy source of all.©
  4. 4. 3. Kinetic Energy: When an object is subjected to a force it accelerates and its speed increases. The forces used in accelerating this object are stored as Kinetic energy. In simple terms, it’s a green technology that literally allows you to create renewable power by walking, thus reducing your personal carbon footprint. At some level we have already been using this form of energy in consumer products. For example a motion powered watch or calculator etc. Kinetic energy will be a resource in future. Big energy giants and companies like Shell, GE and IBM are investing in its research and technological development. With these companies investing in its research, the future looks even brighter. This energy will be generated and stored at industrial level. There is some exciting work already underway in various industries. Volvo Car Corporation (VCC) has received a grant of 6.57 million Swedish kronor (US$1.05 million) from the Swedish Energy Agency to develop and test a flywheel kinetic energy recovery system in a joint project together with Volvo Powertrain and SKF.©
  5. 5. 4. Water Energy: Water power is viewed as something that could potentially be the solution to powering everything we use on planet earth. Water contains a tremendous amount of potential energy if it can be utilized correctly. There are several ways of generating power using water. But the simplest, oldest and most widely used method remains the Hydro Electric power. It is the electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 19 percent of global electricity consumption. It does need heavy investment costs if produced at industrial level but it can easily be produced at small levels. This makes it an obvious easy choice for several rural areas across the world. Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. Approximately two-thirds of the economically feasible potential is still available to be developed. Untapped hydro resources are still abundant in Latin America, Central Africa, India and China which make it the best candidate for future investments and development.©
  6. 6. 5. Wave Motion Energy: This is relatively a new system of producing power and we are still learning on the best ways of tapping this to its full potential. Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter. The Aguçadoura Wave Farm was the world’s first wave farm. It was located 5 km (3 mi) offshore near Póvoa de Varzim north of Oporto in Portugal. The farm was designed to use three Pelamis wave energy converters to convert the motion of the ocean surface waves into electricity, totalling to 2.25MW in total installed capacity. It was completed in 2008. Other wave farms, with other companies involved, have been proposed. This area has potential of huge investments and reaerch in future.©
