The most common renewable energy sources are biomass‚ hydroelectric‚ geothermal‚ wind power and solar power. Sunlight is the source of most renewable energy power; the sun can be used to produce solar energy which is electricity for heating‚ cooling‚ lighting homes and transportation. [1] Non-renewable energy is energy that comes from the ground and

PROBLEMS SCIENTIST FACE IN PREVENTING THE REOCCURENCE OFMALIGNANT MELANOMA. Melanoma is the deadliest form of skin cancer. Whether it’s called malignant melanoma or simply melanoma‚ this cancer can metastasize (spread) rapidly. With early detection and proper treatment‚ melanoma has a high cure rate. Early detection and treatment are possible because melanoma typically begins on the surface of the skin. It develops when melanocytes are damaged‚ which causes these cells to grow uncontrollably. As

Energy is the fuel that runs the engine of the world economy. Believe it or not our need for energy is not primarily to run economies but intrinsically to create order in the world. Wind energy Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing‚ grinding grain‚ and for irrigation. Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been
