Energy consumption essay

Hence renewable energy might be answer to environmental and economic woes of current energy mix. If we compare seriously all costs of various alternatives of power, we’ll conclude that renewable energy should get dominant attention of our policy makers. To achieve rapid progress in the sector it is essential that Industrial base be developed to ensure supply of adequate technology and continuous innovation directed towards efficiency. This should be coupled with robust demand which will also need government support. Overtime Solar PVC, small wind mills, Small hydro will become part of common man’s life in India. This is best way to electrify whole India in a sustainable way .

Many governments worldwide have initiated energy-management programs, such as Energy Star , an international standard for energy-efficient electronic equipment that was created by the United States Environmental Protection Agency in 1992 and has now been adopted by several other countries. Energy Star reduces the amount of energy consumed by a product by automatically switching it into “sleep” mode when not in use or reducing the amount of power used by a product when in “standby” mode. Surprisingly, standby “leaking,” the electricity consumed by appliances when they are switched off, can represent as much as 12 percent of a typical household’s electricity consumption. In Australia, standby power is a primary factor for the country’s increased greenhouse gas emissions — more than 5 megatons (CO2 equivalent) annually.

Not all wavelengths of light can support photosynthesis. The photosynthetic action spectrum depends on the type of accessory pigments present. For example, in green plants, the action spectrum resembles the absorption spectrum for chlorophylls and carotenoids with absorption peaks in violet-blue and red light. In red algae, the action spectrum is blue-green light, which allows these algae to use the blue end of the spectrum to grow in the deeper waters that filter out the longer wavelengths (red light) used by above ground green plants. The non-absorbed part of the light spectrum is what gives photosynthetic organisms their color (., green plants, red algae, purple bacteria) and is the least effective for photosynthesis in the respective organisms.
