Loft insulation and double glazing.
Sunlight is a resource that doesn't run out. So if that energy is used instead of something else such as fossil fuels, then this helps to conserve those fuels.
one way is to conserve resources is to reduce the amounts that are used
Heat is used to cook our food, to warm our houses, and to keep us alive in the freezing winters.
Nuclear plants produce energy rather than conserve it. They generate electricity by harnessing the energy released from nuclear reactions. While they can help meet energy demands without relying on fossil fuels, they do not directly contribute to energy conservation efforts.
Possibly you are talking about drip irrigation.
Green-houses are used to store many of different plants from outside, when the conditions are not suitable for them, contolled temperature and artificial lightning are used is Green-houses to help the plants grow.
Heat insulators are used to reduce heat transfer between objects, such as in building insulation, protective clothing, and food packaging. They help maintain temperature stability, conserve energy, and protect against extreme heat or cold.
Common methods to heat houses include furnaces, boilers, heat pumps, electric heaters, and fireplaces. These systems use various sources of energy such as natural gas, propane, oil, electricity, or wood to generate heat for warming indoor spaces.
In cold waters, assume the HELP position (Heat Escape Lessening Position). This is where you roll up into a ball with your chest against your thighs, while gripping your ankles. This will allow your body to retain heat longer, and could save your life if it gives more time for a ship to come by.
the Victorians used coal sometimes wood
In a hyrid car, when you brake the energy that is used is transferred back into electricity instead of totally lost as heat energy.
Geothermal energy is used for generating electricity and heating buildings. It harnesses the heat stored beneath the Earth's surface to produce power through geothermal power plants or directly through geothermal heat pumps for heating and cooling systems.
