Current info about the types and effects of water pollution is not always the easiest thing to locate. Fortunately, this report includes the latest energy and pollution info available.

Passive solar energy refers to collection of solar energy simply by the design and materials used in building construction. A greenhouse is probably the best example of a passive solar collector. Passive solar heating involves the design of homes and other buildings to make full utilisation of direct sunlight for heating purposes. Houses can be designed with large windows in the south facing walls and small windows in the north facing walls.

China is home to more than 100 wind-turbine manufacturers and some 400 solar-panel companies. The country has quickly grown into the world’s largest maker of photovoltaic cells. China’s five-year plan that starts in 2011 will include even higher standards and subsidies to support clean energy development.

Most of this information comes straight from the pros. Careful reading to the end virtually guarantees that you’ll know what they know about the effects and types of water pollution.

Powerboats easily supply this from their engine driven alternator, but sailing boats often have to limit equipment use to conserve power, especially on longer passages. Water turbines provide a neat solution, and while they may slow the boat down slightly in light winds, they are generally powerful enough to only be needed intermittently-perhaps for just a few hours each day. Power is generated using the piezo effect that occurs when a button is pushed. That is to say, when a crystal is compressed it emits a tiny bit of electricity which is harnessed and used to power this device.

Power failures deprive cities of energy for two to four hours on a daily basis, while rural areas face power cuts lasting up to 20 hours per day. In addition, experts predict a further increase in energy consumption, with per capita electricity demand rising from a current level of 660 kWh per year to as much as 2,000 kWh over the next 10 to 20 years.

China is telling their banks to support PV companies with strong loans, both for domestic and foreign. So the real irony is that I am going to China not just to find products, but to find financing (preliminarily offered) to install those products in the US. China plans to spend about $200 billion on renewable energy over the next 15 years, including solar energy and wind power, as well as biomass. Its solar-power ambitions could be limited, however, because of a shortage of polysilicon, the raw material used to make solar cells.

So now you know a little bit about the types and effects of water pollution. Even if you don’t know everything, you’ve done something worthwhile: you’ve expanded your knowledge.
