different technologies can be used for micro-CHP, including stirling engines, rankine engines, internal combustion engines, and fuel cells.

Fuel cell based micro CHP units in homes and commercial buildings can help the electricity grid assimilate more renewables according to the Technical University of Denmark.

Scientists published a report explaining the need to create a market for electricity services to draw new technologies such as micro CHP into wider use and accelerate the cost reduction needed for general consumer uptake. Read More

renewable geothermal heat source, which will supply between 40 and 50% of our heat requirements.

The Technical University of Delft want the campus to be energy neutral by 2020. Part of this metamorphosis involves a new smart heat grid.

TU Delft is converting the existing heating system into a smart heat grid that provides heat at various temperature levels from various conventional and renewable heat sources.

Hydrogen Power, Pros & Cons

renewables, climate change, Geothermal energy, wave power, energy market, pros and cons of Geothermal, Solar Power, Wind Power, Thermal Power, hydro

Hydrogen fuel cells are highly efficient and less dangerous than gasoline

Hydrogen is the cleanest energy source we know of. In a electric fuel cell electricity is created by combining hydrogen and oxygen.

Without combustion, the only byproducts are water and heath. 

Although hydrogen can be produced from diverse renewable resources already, the main challenge is cost. Most of the cost of creating hydrogen by electrolysis, comes from buying power from the grid. So new research is good for the future of affordable hydrogen.  Read More

Shale Gas, Pros & Cons

Fracking, gas, power, electricity, power plant, renewables, energy, electricity

Fracking uses toxic chemicals

Shale gas requires an aggressive method of collection since it is buried deep in the earth under many layers of shale.

The most popular method of collecting shale gas is hydraulic fracking, a relatively new technology, which has become quite controversial. 

Wyoming is the first US state that has reached a settlement on January 26, 2015 with oil and gas frackers. Now they have stricter chemical disclosure rules and have to be more transparent. Read More

Solar Power Pros & Cons

At this moment, researchers are evendeveloping solar panels who can produce energy at night!

Are there any cons for Solar Power? Yes of course but households can contribute with solar panels on top of their houses and so reduce greenhouse gasses.

But… These systems tend to be small scale and are certainly not the silver bullet to solve our energy challenge. Solar Power would make a huge difference, as one aspect of a multifaceted solution. Read More

Energy from Tar Sands Oil, Pros & Cons

The discharge that accumulates in highly toxic waste ponds pose a huge threat to wildlife.

In the United States a large supply of oil sands are found in Eastern Utah. These deposits of bitumen or heavy crude oil have the ability to generate about 12 to 19 billion barrels from a number of prominent sites. Canada also has oil reserves op 170 billion barrels. Read More

Fusion Power, Pros & Cons

Fusion energy has the potential to provide a sustainable solution to European and global energy needs

Is Fusion Power the clean power for the future? Fusion is the process which powers the sun and makes all life on earth possible.

Energy is produced by fusing together light atoms, such as hydrogen, at the extremely high pressures and high temperatures which exist at the centre of the sun (15 million ºC).

At the high temperatures experienced in the sun, gas becomes plasma.  Read More

Wind Energy Pros & Cons

Wind Power, new energy, sustainable climate solutions

Extol winds is amongst the first to achieve the stringent GL-2010 guidelines for it 1 MW ‘Ex-55’ model.

Wind energy is one of the oldest sources of power in human history. Wind power was used to pump water for generations.

At this moment there are all kind of wind generators.

From very big stations build on land or sea, to small ones. Mexico introduced a few months ago even an Hybrid Solar / Wind Energy Tower. Read More

Geothermal Energy, Pros & Cons

Renewable energy, renewables, geothermal energy, climate changeGeothermal energy is generally considered environmentally friendly. There are a few polluting aspects of harnessing geothermal energy, but these are minor compared to the pollution associated with conventional fuel sources (e.g. coal, fossil fuels).

The carbon footprint of a geothermal power plant is minimal. 

Further development of our geo resources is considered helpful in the fight against global warming.

Wind mill park at the North Sea

Funding for the construction of the largest wind farm in the North Sea is agreed. The project has a total budget of 2.8 billion euros.

The wind farm will be build about 85 miles up the coast from the north of Holland.

Windmills on the sky building generate 15% less energy

the wind yield could have been up to 15%

Wind turbines set wrong. The wind yield could have been up to 15%

The Bahrain World Trade Center was the first Tower with integrated wind turbines in the world.

Now it appears that the designers have not thought carefully about the orientation. 

If the turbines had been placed exactly opposite, the yield of the turbines had been nearly 15 % higher, concludes Professor Bert Blocken TU Eindhoven.

In theory you should be able to generate up to 31% annually more energy with the rearward placement of the turbines calculated Blocken.
