“And the world will perish soon”… yes, that’s what Michel de Nostredame (aka Nostradamus) and the Mayan Calendar predicted and sooner or later their predictions will not prove to be the wrong ones. Most of the sources of energy that we use are non-renewable and some others end up being threat to nature – Earth. The fear that most of the energy we use they are rapidly being used up and will be exhausted soon while few other resources are danger, is creating a sort of energy crisis in the world. Now how to overcome the impending energy crisis?- keeping in mind that the sources don’t pollute our environment and the future generation too doesn’t have to suffer.
All forms of energy come from sources like the sun, water and fuel. Also, these forms of energy can be changed to forms of other. Alternative energy, however, is any form of energy that does not come from fossil fuels (about which everyone of us is familiar about), nor does it have a greater impact on environment, negatively (in a way reduces long-term ill consequences and effects). So here we go with the top 10 alternatives which can be replacements for the fossil fuels and are replenishable, causing less threat to our planet.
Another type of nuclear fusion which can become an extremely good source of energy is Hydrogen, which contains large amount of energy in its chemical bond.This chemical in the form of energy, changes into electrical energy when reacts with oxygen and produces electricity in fuel cell. Also, when blended with natural gas ,becomes a transportation fuel, thus is a good candid as fuel. As a potential fuel for motive power, (natural agents like water, streams, wind etc) imparts motion to machineries and vehicles including cars and boats. Though, naturally, hydrogen is in abundance, but it can also be generated by reforming hydrogen production, water electrolysis or by other methods.
2. Uranium-The Nuclear Power
In a nuclear power station, when nuclear fission takes place, it produces a lot of heat energy. This heat energy is used used for producing electrical energy and turn the steam turbine. As the turbine turns the generator, it creates electricity, Nuclear power (uranium), an alternative power source uses the nuclear fission of uranium to generate heat and, then, through a heat transferring mechanism and turbines, it creates electricity. This steam turns the turbine to produce power, which is connected to a generator. This power does not solely rely upon natural phenomena to create or form or produce their power as it does not use fossil fuels or other non-renewable resources in the production of energy.
3. Natural Gas
This is an alternative to conventional fuels like petroleum, coal etc. When used in vehicles like cars and trucks, natural gas produces less harmful emissions than gasoline or diesel.Natural gas is useful as a fuel and as a raw material too. It is used as an energy for industrial purposes like making fertilizer, antifreeze, fabrics, and pharmaceuticals; for manufacturing chemicals like ammonia, propane and acetic acid. It is also used as a heat source in making steel, cement, glass, bricks, ceramics, tile, food products and many other commodities. As a fuel, it is used for heating and power generation. Compressed Natural Gas (CNG), which is a promising alternative source of energy is used as a fuel for vehicles.
4. The Green Energy-Algae
Algae are marine organisms which produce energy by way of photosynthesis, like most other plants. The energy comes in the form of oil or biomass. When properly harvested, this oil gets converted to bio fuel, which is usable for all modes of transportation. Growing algae for biofuel does not only provides a viable source of alternative energy, but also yields importance in economic benefits. This green fuel uses photosynthesis to capture the energy from sunlight and produce carbohydrates and oxygen, creating a natural biomass oil product.This lipid oil is used to make biodiesel for trucks, cars, and airplanes. Using algae as an alternative fuel could never be compensated by any other fuel nor could be competed economically with fossil fuels.
5. Biomass Energy
The waste bio-mass like cattle dung, plant residues and sewage, etc, on fermentation in the absence of air produces a combustible gas called bio-gas. This biofuel ,can develop as a good source of energy as it causes less pollution than what the fossil fuels does. This clean renewable energy resource is derived from the wastes of human and natural activities. It excludes organic material, transformed into substances by geological process. Wood, wastes, and alcohol fuels are the largest sources of biomass energy. Some other contributors are agricultural crops, manufacturing wastes, garbage, animal manure, corn stalks, and dead trees, used tired and etc. which in forms of energy are used for cooking and agriculture growth, fuels, power production.
