Development of Wave Generation Plants


The waves that surfers enjoy riding, and the bane of existence for seasickness sufferers on ships and boats can also be used to generate electricity. Using the power of waves in the oceans or other large bodies of water is in actual fact another way of harnessing the power of the wind to generate electricity.
Wave power generation is a relatively new form of generating electricity, and this shows in the number and size of plants currently in operation, generating power using the waves. And unlike wind power generation using turbines, where the basic concept of blades and a turbine is the same, there are still many variants of wave power plants each with unique design characteristics and features.
Still in its infancy, there has not been a fully commissioned plant with an installed capacity larger than 2.5MW. In comparison, a single onshore wind turbine can have a capacity higher than this. Though, with the technological developments taking place, and the feasibility of these power sources with the rising cost of electricity generated using fossil fuels, wave energy development is looking promising.
Funding has been a problem for wave generation plants. Up till now, the world’s first, and largest project utilising wave power, the Aguçadoura Wave Farm, only operated for a few months before funding ran out and investors pulled back.

“Conventional” wind and solar power have been able to grow to the level they are now, in which they are self sustaining, only because they were supported by subsidies and government grants. For wave power to succeed and to enjoy the advantages of scale, investment will need to take place from private enterprise, but also using public funds. This will only be further incentivised with rising oil and gas costs, and a continued push for renewable power generation.

The largest solar farms in the world

Image
Solar energy is gaining in popularity. Most people know solar power as the rooftop panels that are being installed on more and more houses; or projects like Elon Musk’s Solar Roof. However, there are many different applications for solar and many ways energy can be generated using the power of the sun. Electricity is the most common use, but solar energy can also be used to heat water for use in the home, or a swimming pool, etc. Solar arrays can also be used to redirect the beams of the sun to a central point which is then converted to heat energy to drive turbines, much like a coal plant would use a burner – only this time there are no emissions, and just clean energy. A large array of solar panels, be it photovoltaic or thermal, is called a solar farm. Here we take a look at a few of the biggest in the world. Tengger Desert Solar Park Located in China, the world’s largest solar farm uses solar PV panels to generate 1,500MW of electricity. This plant covers 43 square kil

Building Smart Cities, an Energy Transition

Image
Smart cities were once thought to have been a $1.6 trillion market by 2020. Everything from housing, transportation, urban planning, management, would contribute to a smarter neighbourhood enriching the lives of the citizens and residents. From self-driving cars to automated delivery drones, IT networks will become the backbone of the interconnected world. We are not there, yet. Technology is developing and evolving but there is a lack of a common direction, and funding, for many of the players in the market bridging that final implementation gap. Often overlooked by the general public in their desire for a smarter city is also the technical feasibility. Not only do information networks play an important part; but energy is the driver of all of our smart ambitions. To foster the growth of smart cities and to facilitate the transition we must also critically evaluate our energy production and consumption pattern. On a local scale, Electric Vehicles are gaining in popularity

The World’s Longest Transmission Lines

Image
Some of the world’s largest power plants are in some of the most remote locations compared to where the electricity they generate is consumed. The technology of choice for many of these lines is HVDC or High Voltage Direct Current, which allows the electricity generated to be supplied up to hundreds of kilometers away. As the technology is not inexpensive, and requires a stable reliable generation supply in order to be effective. With increasing power demands and strain on electricity systems , developing High, and Ultra High Voltage power lines is only set to increase as new generation projects come online. As population centers are usually located far from hydro-electric plants, it is no surprise that most of the long-distance projects supply power from these dams to large population centers. Rio Madeira transmission link, Brazil Coming in at 2,385km, the Rio Madeira Transmission Link in Brazil tops the chart as the world’s longest. Supplying power from the Santo Antônio an
