In the future natural resources such as coal and oil will be used up. How can we save on resources? What alternative forms of energy are available? Over the last decades, non-renewable natural resources depletion has been expressed as a considerable concern by scientists. Based on the official statistics, fossil fuels accounts for more than 85% of the primary energy production. Therefore, replacement of those with other forms of providing energy such as hydropower, wind energy and sunlight, and also reduction of contribution of, for example, oil and coal is are of today's unavoidable today's requirements. The main consumers of oil are vehicles. Although, nowadays, the increaseing in the of efficiency of cars has been more further taken into account than before, the amount of fuel consumption of them are is still critically high enough to have most contributions in ruining the natural resources. Therefore, by encouraging automobiles manufacturers to invest more on in an exchange for petrol based engines such as electrical and hybrid ones which are highly efficient, usage of energy can be cut down. And also increment of the scale of investment on in public transportation can be extremely helpful. Another destination of fossil fuels is providing electricity. However, there are some alternative ways of producing electricity. For instance, hydropower is a proper way, but it accounts for only six percent of supplying electricity whilst about 71 percent of the Earth's surface is water-covered. Unfortunately, waste of energy is another concern. Not only does it lead to dramatic decrease in sources of energy, but also it causes global warming due to fossil fuels combustion produces carbon dioxide which itswhose emission has detrimental effect on the average temperature of the Earth. So isn't it not the time to modify patterns of energy consumption to save more energy? In conclusion, no longer is are natural resources abundantce. Thus, with by replacing them with other sources which are capable of being renewed and always more available and minimizing the way of life, not an extravagant lifestyle, saving both resources and the environment is possible.
