Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

A New Year For Renewable Energy
Solar Energy News today included three upbeat articles worthy of your perusal:

* RenewableEnergyWorld.com's Top 10 Blogs of 2013

" * #10 SEIA CEO Rhone Resch
* #9 John Farrell
* #8 Chris Meehan
* #7 Emily Hois
* #6 Thomas Blakeslee
* #5 Ron Paulos
* #4 Romeu Gaspar
* #3 Oliver Strube
* #2 John Farrell (Again? Deserves a photo.")
* #1 Jennifer Runyon

* Ten Most watched renewable energy videos of 2013
* Ten Clean Energy Stocks for 2014

* You've never heard of any of them, but here is #1:


* 1. HANNON ARMSTRONG SUSTAINABLE INFRASTRUCTURE (NYSE:HASI).

"Current Price: 13.85. Annual Yield: 6.4%. Low Target: 13. High Target: 16.

I've written extensively about sustainable infrastructure REIT Hannon Armstrong since its IPO in the spring of 2013. Despite its recent run-up on the news of its 0.22 quarterly dividend, I expect the current yield and expected further dividend increases in 2014 will keep the stock from falling, and will likely drive more appreciation

* Here were companies recommended for 2013:


"(CAN'T READ THIS? CLICK ON IT!")

I'VE GOT GOOD NEWS FOR ME. REMEMBER, I SOLD ALL MY STOCKS LAST WEEK. THE DOW JONES INDUSTRIAL AVERAGE FELL 135 TO 15,441. ONLY A DECLINE OF ANOTHER 4865 AND I CAN RE-ENTER THE MARKET.

-The eye of Tropical Cyclone Bejisa never made landfall, staying west of Reunion Island. However, winds as high as 126 MPH were experienced. Bejisa is now moving away, still at 105 MPH.
