The correct option is Solar energySunlight (Solar energy) €œ Non-Conventional.Tidal Energy €œ Non-Conventional.Geothermal energy - Non-Conventional.Fossil Fuels - Conventional.Explanation:There are basically two sources of energy:-Renewable resources or Non-ConventionalNon-Renewable resources or ConventionalThe resources which can renew itself or can be used again and again are Renewable or non-conventional resourceThe sources that cannot be replaced or reused once they are destroyed are called the Non-renewable resources.Renewable resources are replenished naturally and over relatively short periods of time. It is present in unlimited quantityThese are limited resources and consume millions of year to make. So these are used limitedly.It has low carbon emission and hence environment friendly.These are not environmentally friendly because the amount of carbon emission is high.The cost is lowThe cost of these resources is high.Large land area is required for installation of these plantsLess land requirement of installation of these plants.They require high maintenance costs. They require low maintenance cost.For example Soil, water bodies, Sun (Solar Energy), wind, tidal energy, Atomic energy, geothermal, forest, mountains, wildlife, atmospheric resources.Coal, oil, nuclear energy, petroleum, natural gas, LPG, batteries, shale gas, and phosphate are some examples.
