keep the house cooler and wear a jumper
By using less fuel, adjusting the thermostat down, and wearing more clothes.
It results in less heat energy being wasted.
Insulating homes helps to reduce heat loss, leading to lower energy consumption for heating or cooling. By using less energy to maintain a comfortable temperature, homes that are well insulated can help decrease the demand for fossil fuels that are typically used to generate electricity or provide heat. This reduction in fossil fuel consumption can help lower greenhouse gas emissions and combat climate change.
Burning fuel releases carbon dioxide emissions which adds to global warming, therefore less fuel used means less released heat, so if we use 5 gallons of fuel instead of 10 we have cut our fuel emissions by 50%.
No, if the fuel remains the same (the wax) the flame and heat will remain the same.
A biofuel is either a solid, liquid, or gas that is made from recently living material. A biofuel produces less CO2 when burnt than a fossil fuel would. Biofuels are frequently used to power cars, trucks, tractors, etc. and to heat homes or other buildings.
In 1861, people primarily heated their homes using wood-burning stoves and fireplaces. Many households relied on coal as a fuel source, particularly in urban areas, where it was more readily available. Some wealthier homes might have used more sophisticated heating systems, such as hot air or steam heating, but these were less common. Overall, heating methods were labor-intensive and relied heavily on the availability of natural resources.
A fuel with an ignition temperature less than the room temperature would spontaneously ignite - it would not be suitable for fuel because it would burn itself up before it could be used to power an engine.
It really depends HOW the conversion is done. The usual process is to burn the coal; if this is done, the next step is to use a heat engine, and the efficiency of a heat engine is limited in theory by the Carnot efficiency. Of course, in practice, heat engines will be even less efficient than the theoretical Carnot engine.However, if you could find a practical way to use the fuel directly in a chemical reaction (basically, a fuel cell), the resulting efficiency could be much higher.
It uses less fuel (electricity) and that elecriticy is converted more into infare rays (light)and less thermal energy (heat).
Less heat
It provided a more efficient way of getting heat from the burned fuel since it does not produce as much draft as a standard fireplace, and there is less loss of heat.
