Solar Energy is already being harnessed in many part of the world and it has the potential to provide several times the current world energy consumption if properly exploited.
Globally, the sun provides 10000 times the energy humanity uses
When
the dramatic discovery of the ozone hole in 1986 forced the banning of
chlorofluorocarbons (CFCs), the refrigeration industry switched
to hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs).
HCFC¹s are also ozone depleting substances but less so than CFCs.
Meanwhile, both HCFCs and HFCs are potent greenhouse gasses.
Greenfreeze uses hydrocarbons as the
blowing agent for the insulation foam and for the refrigerant.
Hydrocarbons are completely ozone friendly, and used in refrigeration
have minimal global warming impact.Hydrocarbon technology is
not dependent on patented foaming agents and refrigerants. The
operating costs are lower, and the maintenance is easier than with HCFC
or HFC technology.
Wave powerThe
World Energy Council estimates that wave power could produce two
terawatts of energy each year. This is twice the world's current
electricity production, and is equivalent to the energy produced by
2,000 large oil, gas, coal and nuclear power stations. The total
renewable energy within the world's oceans, if it could all be
harnessed, would satisfy the present world demand for energy more than
5,000 times over.
The earth's core is very hot! If we can tap into this renewable source of energy, we will be able to satisfy a large chunk of our energy needs while simultaneously cutting down emissions and pollution dramatically.
This article is about how the Persian Gulf is being polluted due to heavy transportation of oil rigs. "Due to the war and high rate of water evaporation, extended drilling and oil extraction, pollution of the water has increased alarmingly."
Habitat for Humanity has gone global, and is engineering creative solutions to put the people of the world under a roof. Their programs differ depending on the region.
