Batteries May Power Future Of Auto Industry Morgan Stanley Team, Morgan Stanley For some years now, many industry watchers have predicted the demise of traditional gas-guzzlers and the rise of electric cars. Yet, despite the advent of hybrid vehicles, better and cheaper batteries, and the entry of high-performance luxury electric competitors, the former continues to dominate roads globally.
Radiant energy is energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays. An example of radiant energy is the source of energy used in radiation therapy.
Visible light such as sunlight carries radiant energy, which is used in solar power generation. In radiometry, radiant energy is the energy of electromagnetic and gravitational radiation. The SI unit of radiant energy is the joule (J). The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time.
