Saturday's catastrophic earthquake in Nepal occurred because of two converging tectonic plates: the India plate and the overriding Eurasia plate to the north, the U.S. Geological Survey said. Tectonic plates are the large, thin, relatively rigid plates that move relative to one another on the outer surface of the Earth.aturday's catastrophic earthquake in Nepal occurred because of two converging tectonic plates: the India plate and the overriding Eurasia plate to the north, the U.S. Geological Survey said.

Reducing your energy consumption. One important way to reduce your energy consumption is to choose energy efficient appliances when you replace old appliances. However, there are also steps you can take now to reduce your energy bills at little or no cost.
Energy consumption calculation. The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt: E (kWh/day) = P (W) Ã t (h/day) / 1000 (W/kW).lectricity cost calculation. The electricity cost per day in dollars is equal to the energy consumption E in kWh per day times the energy cost of 1 kWh in cents/kWh divided by 100 cents per dollar:
