NEW YORK (CNNMoney) â Thanks to Coloradoâs new pot tax and a quirky state law, residents may get a special one-time tax refund next year. The total could be about $59 million. Thatâs how much the state expects to collect from taxes on the sale of recreational marijuana, which Colorado legalized last year.
Wave energy, also known as ocean energy or sea wave energy, is energy harnessed from ocean or sea waves. The rigorous vertical motion of surface ocean waves contains a lot of kinetic (motion) energy that is captured by wave energy technologies to do useful tasks, for example, generation of electricity, desalinization of water and pumping of water into reservoirs.
The form of any wave (matter or electromagnetic) is determined by its source and described by the. shape of its wavefront, i.e., the locus of points of constant phase. If a traveling wave is emitted by. a planar source, then the points of constant phase form a plane surface parallel to the face of the. source. Such a wave is called a plane wave, and travels in one direction (ideally). Since energy is. conserved, the total energy in the wave must equal the energy emitted by the source, and therefore. the energy density (the energy passing through a unit area), is constant for a plane wave.
