Since the 1980s, no large-capacity solar distillation plants have been built, mainly for the following reasons: Large installation areas are needed, solar distillation plants have low efficiencies, and solar water desalination has been developed, which in some cases can replace solar distillation (e.g., for medium-size communities).

Solar distillation is the process in which solar heat is used to purify water from an impure water source by evaporation and condensation. When solar distillation is used to purify water from saline water, the process is also called solar desalination. Desalination converts saline water with high salt content, about 3.5% by weight in seawater and about 0.6% in brackish water, into fresh water suitable for drinking and other purposes. Use solar energy can be used for desalination, either as thermal energy through the use of solar thermal collectors or solar ponds, or as electricity. mainly through the use of photovoltaic cells.

In recent years, there has been a greater understanding of the role of automotive emissions as environmental pollutants. Sulfur dioxide, nitrogen oxides, and carbon monoxide degrade the earth’s atmosphere and are health hazards. Carbon dioxide adds to the atmospheric buildup of greenhouse gases and in turn accelerates the process of global warming. (more…)

The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (more…)

Brazil produced about 18.5 million metric tones (20.4 tons) of processed sugar in the 2001/2002 harvest, with approximately 9.45 million metric tones (10.4 tons) used domestically and the rest exported. Brazilian sugar is mostly derived from sugarcane, a drought-tolerant tropical and subtropical crop containing about 12 to 17% sugars (90% sucrose, 10% glucose) and 68 to 72% moisture. Brazil grew about 272 million metric tones (300 million tons) of sugarcane in the 2001/2002 season, making it second to India in world cane production that year. In 1975, Brazil adopted a Pro-Alcool Program to convert sugar to ethanol to reduce dependence on petroleum imports that were damaging the economy. (more…)
