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.

Norwegian Researchers Hope To Turn Seaweed Into Biofuel
"Having the status of we are wearisome to do is to produce young natural processes to cook oil," held Khanh-Quang Tran, an merge professor in Norwegian School of Science and Technology's (NTNU) Chest of Fortitude and Be in charge Manufacturing. "Excluding, count petroleum oil is created naturally on a geologic being scale, we can do it in proceedings."
Tran conducted introductory studies using sugar kelp (Laminaria saccharina), which grows naturally put down the Norwegian shoreline. His fight keep been published in the learned communiqu Algal Poll.
By small quartz tube "reactors" - which prompt border on concise strong straws - Tran gnashing your teeth the reactor containing a slurry prepared from the kelp biomass and water to 350 degrees C at a definitely enormous rate of 585 degrees C per not enough.
The dispensing, called settled hydrothermal liquefaction, gave him a bio-oil produce of 79%. That cash that 79 % of the kelp biomass in the reactors was positive to bio-oil. A finale be trained in the UK using the actual species of kelp yielded directly 19%. The out of sight, Tran held, is the swift heating.
Biofuel has yearning been seen as a emerging way to intimate shift planet towards a more sustainable and become rough nonsexual lifestyle. The senses is simple: petroleum-like fuels prepared from crops or substances boost up CO2 as they grow and free that actual CO2 like they are burned, so they are truly carbon-neutral.
In its report "Tracking Buff Fortitude Advance 2014, the Mixed Fortitude Dresser (IEA) says that biofuel production large-scale was 113 billion litres in 2013, and may perhaps last 140 billion litres by 2018.
That may acceptably border on a lot - but the IEA says biofuel production apparition need to grow 22-fold by 2025 to cook the come to of biofuel the world apparition need to discern global temperatures from getting bigger more than 2oC.
The hitch-hike is the biomass feedstock. It's rather easy to change hard skin or sugar beets inside ethanol that we can hypodermic designate inside our petrol tanks. But using provisions biomass for fuel is more and more stiff as the world's population climbs towards 8 billion and outer.
To get a quantity of this hitch-hike, biofuel is now created from non-food biomass together with agricultural residues, land-based energy crops such as fast-growing grass and grasses, and maritime crops such as seaweed and microalgae.
All of these feedstocks keep their challenges, eminently population that are land based. At lowest aspect of the issue is the fact that crops for biofuel may perhaps potentially dislocate crops for provisions.
Excluding, seaweed offers all of the advantages of a biofuel feedstock with the extend benefit of escalating, not impossibly, in the sea.
But bear big pieces of greasy, briny kelp inside biocrude is a pressure, too. Some studies keep used catalysts, which are expand chemicals that can intimate make the process go more speedily or with pleasure. Excluding, catalysts are by and large cherished and appeal catalyst recovery.
The UK be trained that resulted in a 19% produce used a catalyst in its process.
Tran says the frame of his process is that it is rather cheerful and does not need a catalyst. The enormous heating rate moreover fight in a biocrude that has molecular properties that apparition make it easier to refine.
But Tran's experiments were what are called viewing tests. He worked with luck reactors that were small and not ready to go for an strict scale. "In the function of you wish to scale up the process you keep to act with a dispersion reactor," or a reactor with a constant dispersion of reactants and products, he held. "I otherwise keep a definitely good idea for such a reactor."
Steady though the introductory tests gave a produce of 79%, Tran believes he can bring up the fight tedious more. He's now looking for strict associates and extend funding to cope with his research.

Costa Rica Has Used Only Renewable Energy Since The Start Of 2015
Share on Tumblr
FOR ALMOST THREE MONTHS THE CENTRAL AMERICAN COUNTRY HAS RUN EXCLUSIVELY ON RENEWABLES.
Since the start of the year, Cost Rica has not burned fossil fuels for power and has been able to rely on renewable energy alone to power its country, which was made possible due to Costa Rica experiencing heavy rainfall, which enabled the country's hydropower plants to generate almost enough electricity to power the entire nation.
SEVERAL RENEWABLE SOURCES HAVE ALLOWED THE COUNTRY TO BE COAL AND PETROLEUM-FREE.
In addition to hydropower, wind, solar, and geothermal energy have made it possible for Costa Rica not to require any petroleum or coal to keep electricity flowing. That being said, the country does have an advantage over other countries in that it is small, with fewer than 5 million people, it does not have a massive manufacturing industry that would need power for operation, and it is home to plenty of volcanoes, which makes it easier for the country to tap into different renewable sources.
Nevertheless, the fact that the country has managed to run on only renewable energy for over 75 days is still nothing short of remarkable.
80 Percent Of Costa Rica's Renewable Energy Comes From Hydropower.
While 80 percent of its renewable power comes from its hydroelectric plants, about 10 percent comes from geothermal. The country is seeking to evolve its geothermal sector and, last year, the government gave the green light for a 958 million geothermal project that is primarily being funded by the European Investment Bank and Japan.
The project will consist of three plants. The first is expected to generate 55 megawatts (MW) of electricity, which is roughly enough power for 55,000 homes. The other two plants are expected to produce 50 MW each.
Jake Richardson of Clean Technica told Science Alert that more geothermal energy in Costa Rica is good news because "there are obvious downsides of being too reliant on hydropower, especially run-of-the-river systems, which can be hindered by seasonal changes in water flow." Richardson also commented on droughts saying that they can "severely impact power supplies. And there are also some environmental downsides to hydroelectric dams more generally, namely the impact on riparian ecosystems and passing fish."
The bottom line is that it is important for Costa Rica to expand its other renewable energy systems beyond hydropower. If the country were to ever experience a severe drought, it would hinder the nation's ability to produce electricity via water.
