Coal Gasification and the Gasification of Biomass

Article by Steve Evans

Coal gasification has the potential to answer most of the problems of coal power stations and to see us through until improved renewable energy technologies can be developed to replace the use of coal as a main base-load power gernation fuel in many of the world’s nations.

It offers the most versatile and cleanest way to convert coal into electricity, hydrogen, and other energy forms. Furthermore, the first coal gasification electric power plants are now operating commercially in the United States and in other countries.

Energy Saving Ideas

Article by R Miller

In today’s modern economic climate, now has never been a better time to start saving money, and where better to start than at home? Millions of pounds are poured down the drain by millions of households every year. By committing yourself to making a few small changes you could save yourself hundreds every year.

* Use energy saving light bulbs. Energy saving light bulbs may stand on the shelves slightly more expensive than normal bulbs, but can last up to ten times longer and use less electricity. Also, whenever you are not using a room, switch the lights off. This may seem pretty obvious, but only lighting the room you’re in can significantly lower your energy bills.

UPGRADING BIOMASS BY TORREFACTION (1)

In the last decades, energy demand is growth significantly. It is because increasing of economic activity in the world influenced this demand by countries. Energy consumption has exceeded over than 400 EJ annually. As IEA (International Energy Agency) reports, the world’s energy demand will increase by 45% until 2030. The position of fossil energy reaching 80% and oil fuel continues to dominate. Furthermore, the reserve of fossil fuel keeps depleting.

Renewable Energy

Due to the demand for renewable energy sources, there are many businesses that offer solutions for homeowners. The diverse options available to homeowners include products like solar heating panels and geothermal generators. These are good developments for the energy sector because renewable energy is better than the conventional energy harnessing methods available today.

Unlike gas, coal and oil, solar and geothermal energy are renewable. The energy sources for solar and geothermal energy are limitless and readily available. The prices for these energies will remain stable and do not depend on production rates and shipping lines. They do not produce harmful emissions as they generate energy either. They do not produce harmful fumes and noises the way coal based power plants do. They do not pollute the environment.

Energy Saving System: An Idea to Save Energy

Energy crisis is perhaps the most serious problem human civilization has ever faced. Of late, there are a number of devices come up requiring energy to run. With the increasing usage of energy in the form of fuel and electricity, the energy store is at stake. If researchers are to be believed, the time is not far away when energy godown of fuels will empty and even the production of electrical energy would be at hazard as the major source of electrical energy is coal, which is not going to last anymore. 

Energy Saving Ideas For Your Home

Article by Jordan Rocksmith

Trying to conserve energy is not only good for the environment; it will help you save a lot of money as well. There are a few things you can do around your house to conserve energy.

Renewable energy

Our generation is probably more aware of the environment and the affect that our actions have on it. We are aware that we need to pay better attention to what we do and the effect that this can have on the environment. We are also aware of how things such as recycling goods and not wasting electricity can help. We are now encouraged to recycle everything that we can, and rubbish collections now incorporate recycled goods collections in most areas.

Renewable Energy

Renewable Energy is energy derived from resources that are regenerative or for all practical purposes cannot be depleted. Sources such the sun and the wind, can never be exhausted and therefore called renewable. They cause fewer emissions and are available locally. Their use can, to a large extent, reduce chemical, radioactive and thermal pollution. They are a viable source of clean and limitless energy. These are the non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean except for biomass, a renewable source, is a major polluter indoors.

Canada, accounting for extensive biomass supply

Article by Robert Deckard

Sometimes, when one envisions the country of Canada, rolling prairies and green forests spring to mind. This is not an altogether inaccurate picture because the nation still embraces its beautiful and sustainable natural resources. One of these resources, a source of renewable energy, is biomass.

Biomass is simply a supply of something once living able to be burned to manufacture heat for energy production. In various parts of Canada, a traveler may see a series of haystacks or piles of wood chips waiting to be converted into electricity of other forms of power. Unlike coal or petroleum-based sources of energy, biomass is constantly being replenished either by the natural growth and decomposition of trees and grasses or as a byproduct of these same resources. In short, it is a renewable energy.

Why Biomass?

Article by Najib Altawell

Introduction

The name “Biomass” was invented in approximately 1975 to describe natural materials used as energy sources, and refers to organic matter which can be converted to energy. Biomass energy is the oldest source of energy in the human history, as it can be easily dated back to man’s first fire.

From the present available information and data concerning biomass, it’s supply, at the present, counts for 14% of the world energy sources (IENICA, 2007). In the developing countries 4% of energy is derived from biomass, while in the USA it count for 4%, Sweden 14% and Austria 10% (Hall et. al. 1992).
