Energy at home: technologies for intelligent consumption

Energy is an essential part of our daily lives. No one can survive without it. The various environmental protection initiatives are now helping to make use of environmentally friendly and efficient energy sources. The idea is to produce energy that is accessible to all while at the same time helping to combat the greenhouse effect.

Energy needs

Current household energy needs, both in terms of quantity and type, depend on each context. The use is not the same in rural areas, in urban areas and in different countries of the world. In any case, wood is still the main and most exploited source of energy. Concerning electrical energy, it is mainly used for lighting if it is low. In industrialized countries, electricity remains the most common source of energy. It is used for heating, air conditioning and transport (electric cars). In addition to electricity, there is also solar energy. This is captured by photovoltaic panels before being distributed to heat, light or acclimatize a house.

Heat pumps

Heat pumps are also among the domestic energy technologies recently launched in France. Instead of transforming energy into heat, they move it around. Their efficiency is reliable. What's more, heat pumps have a better future. Cogeneration, in particular, is an interesting technological innovation. It collects the heat emitted by a power plant. On a limited scale, cogeneration is dedicated to homes. Its main purpose is to create heat. It is only on a smaller scale that it aims to create electricity. However, this second goal can be worked on since electrical energy is more indispensable than heat. Thanks to this technique, more energy can be saved while limiting energy expenditure.

Solar energy

Solar energy can also compensate for energy consumption in the home. It can be captured in a variety of ways. First, there are solar collectors. These are now booming. They can capture solar energy for lighting and heating a home. However, in the long term, it must be combined with heat storage. Then there is passive solar heating. There are no technological elements in passive solar heating. It is still little used. When heat is produced, heat losses are limited. This system encompasses the amount of energy needed to keep the house acclimatized. Noting that good insulation is necessary to avoid significant heat loss.
