environmental affairs-based on suite101 free online course(part one)

Here begin the series of blogposts, about environmental affairs and management, based on free environmental tutorial.

Defining sustainable development is not easy. There are descriptions, or definitions, coming from United Nations and OECD, but apart this, individual organizations can adopt their own definitions.

Simple definition of sustainable development can be to ensure a better quality of life for everyone and for future generations.

Dutch solar electricity generating path(part two)

The system consists of thick concrete blocks. These blocks are covered of silicon solar cells, protected by toughed glasses. This system is a modular system.

This solar system is expected to generate 50kWh per square meter per year. This electricity can be used to enlight streets, for household use, or traffic systems.

Solar innovations show raising wave. Governements and businesses are claming their pie in this story.

Dutch solar electricity generating path(part one)

Sustainable energy development has seen solar panels embedded in everything. The new project of North Holland municipality is to install solar panel on a cycle path near Krommenie, near Amsterdam.

The name of project is Solaroad,developed by TNO Research Institute, OOms Avenhorn Group and Imtech. The design is expected to be installed in 2012, but concept was already unveiled.

Renewable Energy(part five):Renewable Energy=Domestic Energy

Future predictions are that with the fraction of our current oil investment, it will be possible to create infrastructures and technologies to replace our current fossil fuel infrastructure with renewable energy infrastructures.

All these future renewable energy infrastructures will create new economies, and will create new jobs for millions and millions of people.

The main source for renewable energy is the sun. The sun energy will not last forever. According to scientist predictions, sun will last around our globe and universe for 5 billion years.

Renewable Energy(part five):More Reasons for Renewable Energy

Why to cut down natural gas, coal, oil use? Because pollution and climate change became excessive.

Such an example of fussil fuel use is the raising of traditional cars in last years. Past years about 50 million cars run on using fossil fuels. But we could mention hot water heaters or airplanes.

We already know, that energy sources are on way to run out. Oil sources are approaching their peak production. So consequently oil sources run out, oil prices will raise.

Gasoline prices will raise high, too and gas fueled cars will stay parked.

Renewable Energy(part four):Distributed vs. Centralized Energy

Centralized generation system is a system, where electricity is generated centrally in large amounts and sent out through power lines to houses and businesses.

Distributed system is different:this system is called distributed generation. Such an example for that could be a neighborhood, serie of buildings covered with solar panels. These solar panels continue in small power plants. These power plants are capable to help neighbors, habitants of these buildings appartments to get some extra electricity. Distributed generation is one of advantages of renewable energy on domestic scale.

Another advantage of renewable energy is its flexibility, because renewable energy can work on small systems for distributed generations, or on massive installations for centralized generation.

Renewable Energy(part three)

The main solution to global energy problems is the upcoming and development of renewable energy, energy which can be renewed again and again.

Renewable energy is avalaible in sun, in water and in wind. It is avalaible in running water and some natural ressources. Renewable energy can be collected  using current technologies and can be also harvested.

Renewable Energy (part two)

Energy, our energy comes mainly from fossil fuels like natural gas, coal, oil. All these fuels are the results of millions and millions of years of creation. All these animals and plants puerished, decayed and compressed under their own weight. Huge amount of energies were stored and captured in the process.

The process is the following:once humans dig up fossil fuels, properly called hydrocarbons, we, the humans burn these hydrocarbons. We call this process oxydizing. The energy resulting from this process is transformed to power cars, or any other machines.

In the main process, Carbon atoms latch on to two Oxygen atoms(O).
