Alternative Energy

Presence of surplus carbon dioxide in the atmosphere has taken center stage in the environmental science. All over the world people are worried about the excess amount of carbon dioxide in the atmosphere because it’s causing undesirable changes in the surroundings such as green house effect, global warming, melting of ice caps on the [...]

This summer, Anoka, Buffalo, North St. Paul and 8 other Minnesota cities are gearing up for the production of wind energy. They will use recycled turbines for this purpose. In Buffalo, the work will start from June. After the completion of this project Buffalo will have the honor of the first city with [...]

People want to use clean and green energy and live easy on earth’s resources. Many are changing to hybrid cars and using solar panels side by side with conventional sources of energy. But they hold a grudge. How to store large amount of energy in batteries? Hybrid cars fit batteries for power storage. But [...]

This age is known as electronic age. It seems impossible to run life without electronic goods. They are part and parcel of our personal and professional life. We use many small devices in our everyday life. And each small device needs power. Now devices are becoming smaller with each passing day hence scientists are [...]

We are searching for the alternative energy which can conveniently be used for our industrial and everyday purposes. Wind, water, geothermal and many other alternative energy sources are good and clean and green. But all of them lack one thing or another and don’t seem commercially viable. Researchers all over the world are trying [...]

We are familiar with the importance of intellectual property. It is an essential indicator of the economic growth. Number of patents issued in any country in a year indicates the growth of research and innovative development.

Plants produce energy with the help of photosynthesis. One of the important steps of photosynthesis is splitting water into hydrogen and oxygen and release of energy in this process. Scientists are trying to duplicate this process in the laboratory for the production of energy i.e. hydrogen fuel. Hydrogen fuel is a clean and green [...]

Now scientists are working on metallic nanoparticles to manipulate light in more effective ways than conventional optical materials to tap extra energy from the sunlight. Rice University researchers are paying attention to cup-shaped gold nanostructures that can bend light in a more manipulative manner. Here the cup behaves like three-dimensional nano-antennas.

The life of wind turbine blades can be significantly enhanced by modifying their shape. There is a lot of load on the large wind turbines when the blades rotate and by providing a movable trailing edge to these blades the load can be tremendously reduced. It is similar to the flaps used in the [...]

For the successful takeover of alternative energy over conventional sources of energy we need a good battery technology too for power storage. The devices we want to keep on using need to be recharged. And we all know that recharge takes hours whether it’s our mobiles or laptops. If the researchers from MIT has [...]

We have been hearing about artificial leaves and artificial trees for energy generation for quite sometime. Our life giver green plants are performing this function called photosynthesis for millions of years. The green plants trap sunlight energy and convert it into electrochemical energy. Now scientists want to imitate the process of photosynthesis to [...]

Common man and policy makers both are increasingly being made aware of the importance of clean and green fuels in near future. The governors of 3 states have come forward with a plan to transform Interstate 5 from a freeway dotted by gasoline burners to a sanctuary for eco-friendly cars and trucks. The people [...]

While very small wind energy projects are not normally viable due to the cost and effort involved, a small wind farm in the Clay County could easily start generating power as early as 2010. If this project, called The Romar wind project, starts generating power successfully it will certainly trigger a trend.

By generating 40% of the energy required by wind Spain set a world record last week. When high winds blew through north-west Spain on Thursday, a massive 11,180 MW was generated. Of course the wind energy farms were helped by one of the strongest spells of fierce winds experienced by the region recently.

We come across scores of people unmindful of giving back to nature what they are taking and consuming the resources of nature, haphazardly. But we also come across a privileged few who care about environment and their surroundings and they believe in consuming less and utilizing the resources of nature intelligently. Veljko Milkovic belongs [...]

We use helicopters for medical emergencies, search operations, traffic reporting or protecting celebrity privacy from paparazzi. They are loud, give us bumps (not birthday bumps) and are considered not very efficient and comfortable for daily travel. But NASA wants to give them a makeover. They are researching into shape of rotor blades and material [...]

This feeling is making inroads into many hearts and minds that we need clean and green fuel. Hydrogen is the simplest element known to us. Its atom contains just one proton. It is also lighter than air and doesn’t exist alone on this planet. It is always found in combination with other elements. People [...]

Geothermal energy falls under the category of renewable energy source because the water is replenished by rainfall and the heat is continuously produced inside the earth. Geothermal energy is derived from heat within the earth. People can use the steam and hot water created inside the earth to heat buildings or produce electricity. Wondering [...]

If you think planting trees is going to save the planet from global warming, you’re thinking in the right direction but a problem — we may call it a problem due to the situation we have gotten ourselves in — with mother nature is it takes its own good time to show results. [...]
