- Renewable and Sustainable Energy
Instead of relying too much on Diesel fuel and Coal to generate the majority of Philippine's Electrical energy Supply, we can concentrate more on renewable and sustainable source of energy such as: Hydro Power, Solar Power, and Wind Power. We have too many black outs.

GALE VERTICAL AXIS WIND TURBINE The GALE™ line of vertical axis wind turbines has specific design considerations that make it a versatile and environmentally friendly product. Some key benefits that have helped GALE™ blow past other wind turbine products:

Solar Power
- Mud Heat-Storage Solar Greenhouse
- Here is a webpage that goes into detail on the mechanism of Solar Solar Hot Water, Heating and Cooling Systems Hot Water, Heating and Cooling Systems.
- Solar water heaters -- also called solar domestic hot water systems -- can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use -- sunshine -- is free. source: energy.gov.
Hydro Electricity
Ocean Current - Tidal Stream Generators
 |
These Tidal or Sea Current generators can be installed at the sea bed of any of the straits in the Philippines. With floating (anchored) platforms to mark the location of the generators.
The platforms can also be built big enough to hold a standing windmill to generate electricity. |

Locating wind farms out at sea can reduce visual pollution whilst providing better accommodation for fishing and shipping lanes. In addition, the wind is typically more consistent and stronger over the sea, due to the absence of topographic features that disrupt wind flow.
OTEC - Ocean thermal Energy Eonversion

Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work, usually in the form of electricity. However, the temperature differential is small and this impacts the economic feasibility of ocean thermal energy for electricity generation.
The most commonly used heat cycle for OTEC is the Rankine cycle using a low-pressure turbine. Systems may be either closed-cycle or open-cycle. Closed-cycle engines use working fluids that are typically thought of as refrigerants such as ammonia or R-134a. Open-cycle engines use vapour from the seawater itself as the working fluid.
OTEC can also supply quantities of cold water as a by-product. This can be used for air conditioning and refrigeration and the fertile deep ocean water can feed biological technologies. Another by-product is fresh water distilled from the sea. Demonstration plants were first constructed in the 1880s and continue to be built, but no large-scale commercial plants are in operation.
Biomas Turbine Generators
Biomass is the organic matter produced by plants. Also it refers to other organic wastes like animal waste, food-processing by-products etc. Everything that is biodegradable is biomass. The solar energy trapped by these plants can be converted to electricity or fuel.
Here is what GE is marketing:
- Biomass Steam Turbines
To help customers reduce carbon emissions and improve fossil plant cycle efficiency, while meeting Renewable Portfolio Standard(RPS) targets, GE developed a line of biomass steam turbines that provide high performance with a small footprint. GE's biomass steam turbine product line offers a compact, high efficiency solution for the 60 Hz and 50 Hz markets that offer a wide range of footprint and efficiency options for ratings up to 250 MW.
Giant King Grass is suitable as a fuel for direct combustion (burning) in 100% biomass electricity-generating power plants. Today, biomass power plants are fueled by agricultural and forestry waste such as corn stover, wheat straw, rice husks and wood waste. The price of agricultural waste has increased dramatically in China and India due to market demand, and in many areas, growing Giant King Grass as a dedicated energy crop is less expensive and more reliable than using waste. Agricultural waste is seasonal, because it is only available after the food crop such as corn is harvested. The corn stover must be gathered over long distances because the yield is quite low, then dried, baled, stored and utilized as fuel until the next agricultural waste crop is available. Reliability, consistency and cost of biomass fuel are the major issues facing biomass power plants today. A dedicated Giant King Grass plantation co-located with a power plant is a cost effective and reliable solution to producing clean electricity.>>Read More

How many homes can a megawatt power?
- Source:http://wiki.answers.com
An average U.S. household uses about 10,000 kilowatt-hours (kWh) of electricity each year. A watt is a unit of power, or energy per unit time, so it's the rate at which energy is being used. A kilowatt-hour (or 1000 watt-hours) is a unit of energy, so 10,000 kWh is how much total energy each household uses over the course of a year.
This means that each household, on average, uses energy at a rate of about 1 kilowatt (1000 watts, which equal to ten 100-watt light bulbs).
One megawatt is equal to one million watts, so for one instant, one megawatt can power 1000 homes.
A better question to ask is how many homes can a megawatt-hour (MWh) provide with energy for one hour? If one home needs 1 kWh of energy for one hour, then 1 MWh of energy can sustain 1000 homes for one hour.
