Aguçadoura Wave Park

For the last post of this year, I want to inform you of the first ever wave farm. Enjoy it and Happy New Year!

Aguçadoura Wave Park is the world's first commercial wave farm. It is located three miles offshore near Póvoa de Varzim north of Porto in Portugal. The farm uses three Pelamis wave energy converters to convert the motion of the ocean surface waves into electricity. The farm was officially opened on the 23 September 2008 by the Portuguese minister of the economy.

Developed by the Scottish company Pelamis Wave Power (formally Ocean Power Delivery), the Pelamis machine is made up of connected sections which flex and bend relative to one another as waves run along the structure. This motion is resisted by hydraulic rams which pump high pressure oil through hydraulic motors which in turn drive electrical generators. The three machines which make up the Aguçadoura farm are each rated at 750kW, giving an installed capacity of 2.25MW, enough to meet the average electricity demand of more than 1,500 Portuguese homes.

A second phase of the project is now planned to increase the installed capacity from 2.25MW to 21MW using a further 25 Pelamis machines.

New Green Complex in Singapore

A new green complex from world renowned architecture firm Foster + Partners will be adding more than a dash of green to the Singapore skyline. As sustainability becomes an essential ingredient to development in this island nation, the UK-based firm is leaving no stone unturned to make good use of alternative energy sources in this 150,000 square meter mixed-use project. As the winning design from an international competition, Singapore’s new eco-complex from Foster + Partners is pushing the green envelope from top to bottom in this sophisticated downtown design.

The complex will fill an entire city block between Singapore’s Marina Center and the Civic District with commercial, residential, retail, hotels, and a ‘green’ link to an Mass Rapid Transit (MRT) station. All facades will be fitted with solar cells and, to help control solar gain, direct sunlight will be filtered through ribbon-like canopies rising from the base of the entire complex to the exposed east and west elevations of the towers.

The canopies will form vertical louvers at the elevations and provide more renewable on-site energy with integrated thin-film solar arrays. Vertical green spaces, and extensive sky gardens are also important components of the towers, further greening the whole structure with natural vegetation and ambient temperature moderation.

The slanted facades are designed to catch the wind and direct it downwards for natural cooling of the ground floor spaces. A rainwater harvesting system, geothermal heating system, chilled beams and ceilings, and an ice storage system for cooling are further enhancements planned for the complex.

Renewable Energy Sources versus Fossil Fuels

In modern western world the demand for energy has increased dramatically in the past century and it will grow even further and harder in the near future than ever before. The need for energy rises with upcoming markets that also need more energy. Energy is needed for cars, buses, and other means of transportation, but also to run our appliances and provides us light. Energy is also important for our safety. At night or in the dark a lot can be stolen without proper lightning. Energy is therefore needed for our development and safety.
The way we use energy today comes from knowledge that has it's foundations in the past century and before. Great men like Newton and Philips have set the path for us today to make proper use of energy. The sources which we use for our energy demand are known as non-renewable energy resources. These sources will be discussed here in the article.

Definition of Non-Renewable Energy Resources

The name really explains it very well. Non-renewable energy resources are natural resources that cannot be recycled or re-grown. These natural resources are fossil fuels like coal, petroleum, and natural gas. It also includes mined resources such as the elements used in the production of electricity (uranium and plutonium, for instance). These resources replenish itself in a quicker rate.
Fossil fuels are very versatile. One of their functions is to generate electricity. In order to generate electricity, fossil fuels are burned through the process of combustion. The energy produced from the combustion process is used to power a turbine. The turbine is responsible for the conversion of energy produced from combusted fossil fuels into electricity.

Coal

Coal is one the most used fossil fuels. It is consider too be the most important energy source to produce electricity. The U.S. produces 50% of its energy supply through the combustion of coal. The coal itself is a brownish-black sedimentary rock which contains carbon and other assorted elements. It is extracted from the ground through underground mining or open-pit mining.

Natural Gas

Natural gas is also used to produce electricity. The electricity is produced through steam turbines and gas turbines. Because the gas contains methane the combustion emits less harmful gasses that have a negative effect on global warming. Thus natural gasses are better for the environment compared to petroleum and coal.
There is also another use for it and that is as fuel for cars. It is much cheaper that gasoline and produces less harmful gasses. The disadvantage of running your car on natural gas is that you need more fuel compared to gasoline and the car needs more maintenance. In countries like Argentina, Brazil, Pakistan, Italy, The Netherlands and India it is used as a fuel for cars.

Crude oil

This fuel is the most talk about for the past year(s). The prices for crude oil have gone through the roof and will be rising even more. The demand is increasing while there is less crude oil available. The term black gold is now more applicable than ever before.
The oil itself is very think in consistency and has a dark brown or greenish colour characteristic. It is a complex mixture of different hydrocarbons.
Crude oil or petroleum has various uses. It can be used as fuel or cars and different industrial machines. It is also used as a raw material for products like plastics, solvents, fertilizers and pesticides.
Although the need for crude oil is high and the demand is rising the available crude oil is decreasing. That leaves us no other option than to look for alternatives.
Non-renewable energy plays a very important role in our daily lives. Non-renewable energy will be needed today and in the future. Because this energy source cannot be recycled or re-grown the reserves are limited. The consequences of the shortages of fossil fuels are experienced today and tomorrow. We will need to use these fossil fuels wisely and will need to shift our focus to other renewable energy source. These are the sources that we need to focus on today and years to come.
