16. Determining energy use

17. Determining cost Item Power needs (watts) A Number of appliances B Hours on per day C Energy/Day= watt-hour = A x B x C = D Kilowatt-hour per day watt-hour x 0.001= D x 0.001 = E Cost per day E x $.10/kwh = F Cost per year F X 365 = G Incandescent light 75w11075x1x10=750750x0.001=0.75kwh0.75 x $.10=$.075$27.38/year CFL lights15w
