RENEWABLE SOURCES-ENERGY EFFICIENCY

Heat pumps are devices with the help of which heat energy is transferred from one environment to another. Heat pumps enable the transfer of heat energy from a lower temperature level system (earth, water, air) to a higher heat level system (central heating or hot water preparation) using additional operating energy (electricity for the compressor) by means of a suitable working medium (freon) . (Heat Pumps: Operation, Installation, Service) Unlike other renewable energy sources such as solar and wind energy, ambient heat (earth, water, air) is available for continuous use throughout the year. With a heat pump, without an additional energy source, it is possible to cover all the thermal energy needs of a house for heating and hot water preparation. HOW THE HEAT PUMP WORKS The principle of operation of the heat pump is simple, you could compare it with a household refrigerator only in the reverse function: it heats instead of cooling. Ambient energy (earth, water, air) is transfe...

Autonomous solar power plants do not need to be connected to the electricity grid for their operation. The main task of autonomous solar power plants is the accumulation of produced energy in batteries in order to ensure energy supply during the night and due to unfavorable weather conditions. In addition to battery accumulators, a regulator for controlled battery charging and discharging is indispensable, and by adding an inverter (DC / AC), autonomous solar power plants can satisfy all types of typical network consumers who need alternating voltage. Such systems are suitable for providing the required quantities of electricity where there is no public distribution network and where the cost of connection to the network is too high. (A new dimension for solar energy- click here) The advantages of autonomous solar power plants are: • easy installation of the system, • longevity, • possibility to upgrade the system, • cheap maintenance, • complete energy independence, • Auto...

Solar lighting is the best choice for garden lighting, because solar lamps, in addition to being practical, save money and energy.   (8 Pack Solar Lights Bright Pathway Outdoor Garden) This type of lighting is easy to maintain and install, and with the correct positioning it can best emphasize the visual effect.   Solar lamps can be placed along the path, next to trees, flowers, stairs or doors, and in that way decorate the complete ambience. If you have a fountain, swing or some sculpture in the yard, then placing a solar lamp in the immediate vicinity is very effective. ( A new dimension for solar energy- click here) How do solar lamps work? For environmentally conscious people, when it comes to garden lighting, solar lamps are a fundamental choice. They work on the principle of converting solar radiation into electricity through solar panels. The energy that accumulates during the day is released when it gets dark and thus illuminates the space around you. (InnoGear...

Today, LED lighting takes precedence over classic energy-saving light bulbs, as well as incandescent light bulbs, but there are still a number of doubts that have arisen from their objective differences compared to old light bulbs. About LED lighting The abbreviation LED stands for "light emitting diode", which is a semiconductor element that transmits current in only one direction and illuminates with electricity. LEDs convert most of the energy into light and therefore consume significantly less energy for lighting. With classic incandescent bulbs, energy is converted into heat, and the incandescent bulb emits light and therefore they consume as much as 80% more energy than LED lighting. LED technology was very quickly recognized as a real revolution in the field of lighting and that is why it has become the standard today. (LED Light Bulbs 60W Equivalent)   It is also used in the car industry. Due to a number of advantages over previous forms of lighting, LED lightin...

Smart plugs are the first easy step into home automation.  (Residential Wiring and Smart Home Technology) Smart home technology is becoming more and more popular day by day, and a large number of brands are slowly launching devices that can help you save time, power consumption, and even improve security inside the home. One of the hit products in this fast-growing sector is the so-called smart plug.   What is a smart plug?   It is a small plug that you plug into a standard socket and then simply plug your device into.  Figure 1- Smart plug You don't have to have anything but a router and a smartphone to install them - devices that can be found in more or less every household. With a smart plug, you take control of devices in the house by sending commands remotely. A cheaper smart plug costs about twenty dollars, and all devices also work with most home assistants like those from Amazon or Apple. The smart plug therefore plugs into a standard socket and c...
