Energy costs are constantly rising, which hits our budget, especially in winter, when rooms heating requires heavy expenses. It has been proven that a significant part of heat, up to 40%, escapes through the windows. They attempt to solve the issue by producing special energy-efficient structures that retain heat in winter and prevent the cold from escaping from the air conditioner in summer. Let’s find out what these energy-efficient windows are and how they work.
To solve the problem of the deficit of fossil fuels, numerous researchers around the world are working on the creation and deployment of alternative energy sources. This is not only about the well-known wind turbines and solar panels. We have selected five of the most interesting and environmentally friendly energy sources of the future.
