Over the last decade, the number of countries researching the potential of biomass and bioenergy for energy services rose rapidly. This contributed to the biomass as solid and liquid fuels, an interesting and promising option among renewable energy sources available. This includes solid waste and biomass, which comprises of charcoal, firewood, energy crops and forestry and agricultural residues to produce heat and electricity, (more…)

The convention aims not only at stabilizing CO2 emissions in developed countries but also at ultimately reducing man-made CO2 emissions globally so as to stabilize the global climate. Environmental degradation cannot be singled out as an independent matter among various global issues. (more…)

In this article, the terms clean energy is being used to take on a broad definition of the issue of new energy. Other possibilities, such as renewable energy or alternative energy sources are determined and usually do not include certain key sectors such as energy efficiency and clean fossil fuels, among others, that are dealing within this article.

In 2006, total world wind generating electricity capacity was around 72,000 MW, producing some 160 terawatt-hours (TWh) per year of electricity. As of the end of 2006, the top wind producers were Germany, with 20,622 MW; Spain, with 11,615 MW; and the United States, with 11,575 MW.

Even so, wind accounts for only about 1 percent of the world’s total energy use. (more…)

Wind energy comes from the mismatched heating of the planet that runs all day and night, heated and cooled by the sun. They are also come as effect of the different between land and sea temperature, and natural barriers such as mountains. (more…)

The hydrogen can come from various sources including fossil fuels, wind, solar, biomass, nuclear, solar thermo-chemical reactions, and solar photolysis. (more…)

The tourism sector is taking an active role in environmental protection. They are becoming aware of the impact generated by the activity and recognizing that their actions affect the social, economic and environmental fate. Moreover, the culture of social responsibility, conducted increasingly by decision makers of different tourist areas, is becoming a new (more…)

You may have unfinished masonry walls in your basement. To insulate them, you’ve first got to create wall studs to hold the insulation material. Using masonry nails, fasten 2×2 furring strips in place vertically, placing them 16 or 24 inches apart (measure from the center of each strip to the center of the next strip). Then insulate as with any other unfinished wall.

Be sure you get insulation in the spaces around unfinished walls, doors, and windows. Because the framing area is narrow, loose insulation must be hand-packed into it.
