Using local energy sources such as lake water, wood waste or even garbage to heat and cool buildings is one way for communities to cut their greenhouse gas emissions — the goal of this week's ...

The slower-speed particles will increase in kinetic energy as a result. Conduction is the most common form of heat transfer and occurs via physical contact. Examples would be to place your hand ...

Solar thermal energy (STE) generators share little technological DNA with rooftop photovoltaic panels, the hardware commonly associated with solar power. Ausra, of Palo Alto, Calif., has built a ...

For example, knowing how heat is transferred and the degree to which different materials can exchange thermal energy governs everything from building heaters and understanding seasonal change to ...

It's called the mechanical equivalent of heat, and it was explored in 1868 ... Calculating the change in gravitational potential energy is fairly easy. The mass was 1.3 kilograms, moved through ...
