Demand = KW Consumption = KWH The difference between demand (KW) and consumption (KWH) is vital to your choices in reducing your energy costs. A simple way to see the difference between demand and consumption is by considering two examples.LIGHTING EXAMPLE: One 100-watt light bulb burning for 10 hours consumes 1,000 watt-hours. or 1 kWh.he difference between demand (KW) and consumption (KWH) is vital to your choices in reducing your energy costs.

Caption: Trabeculae carneae in the left ventricle of the heart, coloured scanning electron micrograph (SEM). The trabeculae carneae are muscular, columnar protrusions found on the internal surface of the ventricles, the main pumping chambers of the heart. It is thought that they help prevent suction that would occur with a smooth surface. Some trabeculae carneae also act as a type of connective tissue, to help bind the heart's muscle tissue together.

There are over 600 known carotenoids; they are split into two classes, xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons, and contain no oxygen). All carotenoids are tetraterpenoids, meaning that they are produced from 8 isoprene molecules and contain 40 carbon atoms.In general, carotenoids absorb wavelengths ranging from 400-550 nanometers (violet to green light). Carotenoids with molecules containing oxygen, such as lutein and zeaxanthin, are known as xanthophylls. 2  The unoxygenated (oxygen free) carotenoids such as Î±-carotene, Î²-carotene, and lycopene, are known as carotenes.
