the sun, photosynthesis
Source of energy is the sun.
Halogen bulbs come in various ratings, as do all bulbs.
The energy for photoshythesis in plants come from the sun.
The energy released in a forest fire originally comes from the sun. Trees and other plants use sunlight to photosynthesize and grow, storing energy in the form of carbohydrates. When a fire occurs, these stored carbohydrates are released as heat and light energy.
Most of the electrical energy we use comes from power plants that generate electricity by burning fossil fuels like coal, natural gas, and oil. Additionally, a growing percentage of electrical energy comes from renewable sources such as wind, solar, hydroelectric, and biomass.
Sunlight.
Energy contained in bonds within a nucleus that is converted to kinetic energy.
Radiation, conduction, and convection come to mind . . .
Most clocks use electrical energy, which can come from either batteries or an electrical outlet. Some clocks, such as wind-up or pendulum clocks, use mechanical energy stored in springs or weights.

The only way to preserve them is not to use them, but it's more sensible to go on using them (which we will do come what may), but to use them more economically, and to use renewable energy where possible
The person using the hand tool supplies the energy needed to use it. That person gets energy from the food he eats.
They usually come with a 1500W setting.
Geothermal energy.
Plants use sunlight as the primary source of energy to carry out photosynthesis. The sunlight is absorbed by pigments in the chloroplasts of plant cells, where the light energy is converted into chemical energy in the form of glucose.
Energy human's get daily is derived from food. Food rich in carbohydrates provide more energy to sustain humans each day.
Most of the energy we use - whether industrial or otherwise (for instance, the food we eat) comes from sunlight. The main exceptions are geothermal energy, tidal energy, and nuclear energy.
