Existing type of alternative energy
alternative energy. Every day, 365 days per year The sun gives us energy in the form of light and heat all year long. But most of the energy it supplies goes unused, while instead we burn carbon fuels, which in trun is become scarce and therefore more expensive to provide. The situation will only worsen for those who continue to rely on fossil fuels, and the time to use solar energy to power our homes is now.

Solar Heating
Typically you will get about 80% saving of that electricity that your electric geyser will use from your solar water heater. Unfortunately only few people can currently buy a solar solution.
An renewable. Its main selling point is you have to pay less for the initial cost. With the heat pump you have a payback period of less than two years. With the solar panel you get a payback of in the region of about four years and with the cheap solar panel in the area of about six years.

Buying a solar system may take about 5-8 years to pay itself, but benifiting of federal tax credits and state, it may be paid much quicker. Solar water heaters also last much longer than gas or electric water heaters. In the meantime, your investment is paying dividends for the environment.

Wind Turbine
Probably the second most fashionable residential source of energy saving is the home wind turbine. Wind energy, like solar, rely on nature to produce energy efficient, with few costs after the first installation.

Green Energy Lighting
To some, the phase out of the humble light bulb which has been a key element of the electrical industry is nothing but an inconvenience. To others, it is a long overdue and important step in reducing carbon emissions and slowing the pace of climate change. To the electrical wholesaler it could be either of the above.
But one thing is certain, whatever your personal standpoint it is also a sales opportunity.

The commonly used metric for comparing energy saving lighting is lumens of output per watt of electrical input. This method is appropriate for omni-directional bulbs such as traditional A-shape lamps and spiral CFLs.

What does the futur hold. I think energy saving may create some jobs in the short term. However, Most of the empoyee will become unemployed once the solar panels, windmill are installed, theres little or no maintenance on them, there will be no reason to retain all employees. I do think we should develop energy efficient in more efficient ways than we have, and for that, there would need to be a reasonable expectation of profit for those who would invest the assets for research.
Green energy is probably looking at making up 10 per cent or so, maybe a little less than that, of our energy mix over time.
