Energy is an essential part of our daily lives. No one can survive without it. The various actions for the protection of the environment now help to exploit ecological and efficient energy sources. The idea is to produce energy accessible to all while promoting the fight against the greenhouse effect.
The current domestic 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 around the world. In any case, wood remains the most exploited main source of energy. Concerning electrical energy, it is mainly dedicated to 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 car). In addition to electricity, there is also solar energy. It is captured by photovoltaic panels before being distributed to heat, light or acclimatize a house.
Heat pumps are also among the recently launched domestic energy technologies in France. Instead of transforming energy into heat, they move it. Their efficiency is reliable. In addition, 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 housing. Its main objective is to create heat. It is only in second place that it aims to create electricity. However, this second goal can be achieved since electrical energy is more essential than heat. With this technique, more energy can be saved while limiting energy costs.
Solar energy can also compensate for home energy consumption. It can be picked up in different ways. First, we note the solar collectors. The latter are now booming. They can capture solar energy for lighting and heating a house. However, in the long term, it must be combined with heat storage. In addition, there is passive solar heating. The latter does not include any technological elements. It is still little used. When there is heat production, losses are limited. This system includes the amount of useful energy to keep the house acclimatized. Noting is that good insulation is necessary to avoid significant heat loss.
