Renewable Source Of Energy – A Solution

August 26th, 2009

What is the definition of renewable energy? Renewable energy is energy generated from non depleting natural assets such as wind, sunlight, tides and rain. They can be used to power our homes, industries and even our vehicles.

BIOMASS ENERGY
The central source of renewable energy, on an inclusive scale, is the use of biomass. Biomass is described as using biological material in the production of fuel. General biomass sources include wood, corn, sugarcane, switch grass and even algae. Biomass makes up approximately 13% to 15% of all energy consumed in the globe.
Biomass additionally includes bio fuel. This is the use of biomass resources such as corn, sugarcane and a host of other sources, to bake fuels that power the worlds’ vehicles.
There is great potential in expanding the employment of biomass to help reduce carbon emissions, to reduce energy prices and reduce the effect of international warming on the environment.
HYDROPOWER
Hydroelectricity (or hydropower) follows biomass as the subsequently leading renewable energy source. It is estimated that hydropower provides involving 3% and 5% of all energy consumed around the globe.
Hydropower produces energy using gravity’ force on falling water. The energy is harnessed using dams to drive turbines and generators.
The biggest hydroelectric dam is now being constructed in China on the Yangtze waterway. This effort has caused the relocation of millions of citizens and the flooding of crucial archaeological sites. Here is much argument about its impression on the wildlife and fisheries that currently exist.
SOLAR, WIND & GEOTHERMAL ENERGY SOURCES
Solar, wind and geothermal energy produce up between .08% and 1.0% of all energies used globally. These eco-friendly sources of energy control the potential to significantly reduce the exploitation of fossil-fuels as the main source of energy in the earth.
SOLAR POWER
Solar power is likely to be the most valuable of the renewable energy sources existing. As extra buildings and homes are constructed, solar expertise can simply be accommodated in its design and implementation. In various countries, incorporating solar technology into novel or existing homes and businesses also comes with monetary incentives such as duty credits, grants and even loans.
The solar energy process involves placing collecting cells and panels in “sun-rich” locations to harness the sun energy. It is next converted to electricity via photovoltaic dispensation.

WIND POWER
The service of wind power to generate electricity is growing by a rate of about 30% annually. It is widely used in Europe, and here is a big push in the United States, led by energy industrialist T. Boone Pickens. His perception is to harness this energy using wind farms off the eastern and western coastlines of the United States, progressively dropping our dependence on oil products.
.
CONCLUSION
The function of renewable energy sources is the mainly environmentally sound method to help reduce overall energy expenditure and the world’s dependence on fossil-fuels. The consumption of renewable energies will also help in providing healthy surroundings for yet to come generations.save electricity with a do it yourself kit

Are Bio Fuels Any Good?

July 13th, 2009

As the name suggests, bio-fuels are fuels that are formed when biological material decomposes. The bio-fuels are mostly derived from plants. Bio-fuels exist in all the three states of matter: Solid, Liquid, and Gas.

The difference between bio-fuels and fossil fuels

Bio-fuels are distinctive from fossil fuels in the following ways:

  • Fossil fuels can take a million years to build while bio-fuels can be made exceptionally fast, in a matter of days.
  • Fossil fuels create enormous amounts of pollution.
  • Bio-fuels are comparatively safer.
  • Bio-fuels are renewable sources of energy As opposed to fossil fuels.

Different types of bio-fuels

Bio-fuels have been categorized into four types: First generation, second generation, third generation, and fourth generation.

The first generation bio-fuels are created from vegetable fats, starch, and sugar, which are in turn derived from food-crops. The first generation fuels are also created from animal fats. Biogas, bio-diesel, and vegetable oil are some examples of this type of bio-fuels.

The second generation of bio-fuels is primarily derived from waste biomass, thus making it a more balanced option compared to the first-generation bio-fuels. Various kinds of alcohols and diesel generated from wood fall into the category of second generation bio-fuels.

The third generation comprises of bio-fuels created from algae. Algae are farmed on sizeable scales for creating these bio-fuels. The algae fuels are exceptionally environment-friendly as they can simply decompose into the soil without harming it.

The bio-fuels in the fourth generation are derived by a method in which micro-organisms are raised to work with carbon dioxide to generate fuel.

Advantages of bio-fuels:

  • Bio-fuels prove advantageous in the following ways:
  • Bio-fuels lessen the burden on gradually-vanishing fossil fuels.
  • Bio-fuels are environment-friendly. They help reduce carbon emissions into the atmosphere.
  • Bio-fuels, especially, bio-diesel prove to be very cost-effective for consumers.

Disadvantages of bio-fuels
Bio-fuels are not bereft of critique. Though beneficial for the natural environment, bio-fuels have their disadvantages, ironically in the environmental purview. Bio-fuels have received critique for many reasons, a couple of which are stated below:

Economists have long debated on the usefulness of first generation bio-fuels when compared to the lack of food they cause. Creating fuel from food crops makes food crops unworthy of human consumption. Some folks believe that being a higher priority than fuel, food should not be farmed for making fuels but for human consumption.  Making bio-fuels requires acres of farming land, thus encroaching upon the natural environment of plants and animals.
