Alternative energy for homes





 

Experts predict a steady increase in prices for basic types of energy. This is not surprising, since the proven gas and oil reserves will be used up within 30 years, and undiscovered will suffice for a maximum of 60-70 years. Therefore, alternative sources of energy has become urgent in recent times. Let us consider briefly the promising alternative energy sources for the home.

The energy of Santana today a solar thermal system (solar systems) are actively used in the hot water supply, heating and conditioning of buildings. Such systems are divided into passive and active.

Passive solar the sun's rays fall directly on objects and devices, there is no possibility of regulation of their intensity. Therefore, they do not guarantee uniform heating and full utilization of energy, but are characterized by simplicity and cheapness. Types of passive solar systems: greenhouses, black tanks, tanks for water heating in summer, glassed loggias and verandas.

In active systems, the rays of the solar collector (suntrap), where it is converted into heat energy. This heat is then piped to the hot water system and heating or to the battery, where as required is used on.

With the help of solar power systems in addition to thermal energy to produce electricity.

Energy petrotranslations installation for individual users are mostly used to generate electricity. Having a power of 50 kW, they can successfully cope with the energy of the cottage. Wind turbines are also used for driving pumps to raise water from different sources.

In such installations, using the wind rotates the wind wheel, which through a gear system transmits torque water pump or shaft generator. Divided into:

vane mallapaty (2-4 blades) — for initial start you need wind speed not less than 5-8 m/s, are characterized by high efficiency and simple design, with a strong wind creates high level of noise;

multiblade vane (18-24 blades) is enough wind speed 2-4 m/s, the noise is not creating, but efficiency is lower, and the increased consumption of materials;

rotary (carousel) — the blades move in a circle, work at a constant low wind speed and no noise, but also low efficiency.

Thermal energy land as an alternative source of low temperature heat can be considered the soil, air, groundwater and surface water, etc., To collect heat, increasing its capacity and transmission to the consumer using heat pumps. In addition to the heating used for hot water and air conditioning.

Types of heat pumps:

ground — heat is collected using stacked below the level of soil freezing horizontal manifold or located in a purpose-drilled borehole vertical probe; able to meet the demand of the cottage is warm, but winter is better to have a backup electric heater;

water take heat from natural reservoirs or groundwater

air is appropriate to use in a warm climate.

Energy biomassanimal today is used in installations for production of electric and heat energy, as car fuel. (biodiesel). In the production process of biofuels can be produced antifreeze, plastic, glue, etc.

With the help of special biogas plants for the house is derived from biomass biogas, which the plant digests into thermal and electric energy.

Energy bodiesi have access to running water, you can use a mini-hydroelectric plant to produce energy for the home.

The energy of the tides

Can be used in places where the difference between ebb and tide is not less than 5 meters (on the ground only 40 such places).

Types of such structures: tidal barriers, dams, tidal turbines.

Energy volnata energy is emitted from the surface waves or due to the change in pressure beneath the surface. Can be used almost everywhere.
