There's no recycling of energy as it gets transformed through usage: electricity becomes warmth, or light (and warmth), or anything else, usually in so much a dispersed flows as it is quite difficult to re-use it.

In a number of circumstances, though, we have also the energy recycling/reusing experience: think at tele-warming for residential and business premises fed by the dispersed calor of refrigerating plants associated to boilers, incinerators, etc. - just so as to make an example.

At the end, it's a matter of scale - the biggest the quantity of used energy the easist the reusage/recycling thereof.

Dr Renato Conti thank you for your contribution to the discussion

Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. The cycling of matter because there are only finite amounts of nutrients available on the earth, they must be recycled in order to ensure the continued existence of living organisms. Microorganisms play a crucial role in this recycling. They are responsible for breaking down dead matter and releasing materials back to the environment. The three main cycles of an ecosystem are the water cycle, the carbon cycle, and the nitrogen cycle. Chemical elements and water are recycled through biogeochemical cycles. The cycles include both biotic and abiotic parts of ecosystems. The water cycle takes place on, above, and below Earth's surface. In the cycle, water occurs as water vapor, liquid water, and ice.This is because, as energy goes through a system, it is slowly lost as heat. But, matter is a constant material, which cannot be lost in any form and is used for another purpose, and gains energy that again collapses by losing energy. Reduces the amount of waste sent to landfills and incinerators. Conserves natural resources such as timber, water and minerals. Prevents pollution and reduces greenhouse gases by reducing the need to mine and process new raw materials. If decomposers were removed from a food chain, there would be a break down in the flow of matter and energy. Waste and dead organisms would pile up. Producers would not have enough nutrients because, within the waste and dead organisms, nutrients would not be released back into the ecosystem. Energy, unlike matter, is a force that cannot be physically held on to or weighed. Because energy transfers always involve heat loss as energy travels from one form to another, it is impossible for that energy to be locked into physical materials that always recycle in the same way that carbon does. Energy is not recycled. It is used to keep living things alive as it passes from one living thing to the next through the ecosystem, but as it does, it is continually degraded to heat and cannot be reused. Matter, often in the form of nutrients, is recycled and reused over and over in ecosystems. As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Elements pass from one organism to another and among parts of the biosphere through closed loops called biogeochemical cycles, which are powered by the flow of energy.

Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. Unlike energy, elements are not lost and replaced as they pass through ecosystems. Instead, they are recycled repeatedly. All chemical elements that are needed by living things are recycled in ecosystems, including carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur. Nitrogen, oxygen, carbon, phosphorus, sulfur are vital compounds which are recycled in the ecosystem through biogeochemical cycles. These compounds transfer from producer to consumer to decomposer and then again into the environment. In the similar way water is also recycled in the ecosystem by water cycle. Recycling prevents the emissions of many greenhouse gases and water pollutants, and saves energy. Using recovered material generates less solid waste. Recycling helps to reduce the pollution caused by the extraction and processing of virgin materials. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. In contrast, the matter in an ecosystem is continuously recycled as atoms are combined and recombined in different ways. Energy, unlike matter, is a force that cannot be physically held on to or weighed. Because energy transfers always involve heat loss as energy travels from one form to another, it is impossible for that energy to be locked into physical materials that always recycle in the same way that carbon does.

Elements pass from one organism to another and among parts of the biosphere through closed loops called biogeochemical cycles, which are powered by the flow of energy. Energy in an ecosystem is a one-way stream. Water that flows down a stream will not make its way back to the top to ride the stream a second time. Similarly, energy will not make it back into the system to be recycled again through matter. This is because, as energy goes through a system, it is slowly lost as heat
