The world has a wide range of energy sources. Fossil fuels, including oil, natural gas and coal–accounted to more than 81 % of the energy consumed in the year 2018. Renewables, such as solar power, wind power, hydroelectricity and biomass, account for 14 percent. Nuclear energy is another 5 percent. Different countries employ different energy sources to balance the needs of their economy and environmental concerns.

Energy is present in nature in many forms, including sunlight and wind, waves, ocean and many more. When harnessed and transformed into more practical forms of energy, like electricity or heat, these are called primary sources. These sources of energy become non-renewable sources of energy when they are exhausted.

Many fossil fuels and some of the other nonrenewable energy sources are causing harm to the environment. For instance mining for oil may take away the planet’s forests. Fracking (hydraulic fracturing) could cause water pollution and earthquakes. Carbon dioxide is released when coal is burnt which contributes to global warming.

Fortunately, some of the most promising sources of energy are renewable and sustainable. Hydropower, wind and solar for instance, can produce electricity without having to search for fresh supplies.

Other renewable energy sources are emerging, including the wave and tidal power. However, in order to be utilized on a massive scale, these technologies must have effective distribution networks. This requires the use non-renewable energy sources to construct these networks. These sources aren’t able to fulfill the majority of our energy requirements. It’s important to remember that the cost of renewable energy equipment have dropped dramatically in recent years and the efficiency of these equipments is growing.
