Generally electricity but come in both.
Space heaters can run on various fuels, including electricity, natural gas, propane, and kerosene. Electric space heaters are the most common and are typically used for indoor heating. Gas heaters, such as those powered by natural gas or propane, are often found in areas where electricity is less accessible. Kerosene heaters are portable and can be used in emergencies, but they require proper ventilation due to emissions.
Answer No, if the current to the baseboard heaters is off they can't run or heat.
Hybrids run either on electricity or on fuel.
At Menards you can buy an outdoor patio heater at http://www.menards.com/main/outdoor/patio-furniture-benches/87-outdoor-patio-heater/p-1651682.htm for $149.99. A patio heater varies in length of life depending on the power source. If you have a propane tank, you can run out if used often in a week. Outdoor heaters are less effective than indoor heaters because outdoor heaters have to work harder to heat the whole patio (cold weather will undo any work already done) while indoor heaters don't have to worry about varying temperatures.
Railroad trains have - and continue to - run on any of three powers: Coal (steam), diesel fuel, and electricity.
The diesels run out of fuel. Electric trains run out of electricity.
Greenhouse heaters can be economical to run, but their efficiency largely depends on factors such as the type of heater, fuel source, insulation of the greenhouse, and local energy costs. Electric heaters might be convenient but can be expensive in areas with high electricity rates. Conversely, gas or propane heaters may offer lower operational costs, especially if prices for those fuels are stable. Overall, optimizing insulation and using energy-efficient heating solutions can enhance cost-effectiveness.
As a fuel it is used to run the generators which produce the electricity.
As a fuel it is used to run the generators which produce the electricity.
No, but if gas is combustible then it may be used as a fuel to run the generators for the production of electricity.
Oil-filled heaters are generally considered to be cost-effective for heating small to medium-sized rooms. They are efficient because they retain heat for a longer time, even after being turned off, which can reduce electricity consumption. However, their overall running cost depends on electricity rates and how often they are used. In comparison to other electric heaters, they can be cheaper to run, especially for prolonged use.
All gasoline cars run on both - electricity is required to create the spark which ignites the fuel/air mixture.
