The world’s energy crisis
The world is gradually marching towards a severe energy crisis, what with an ever-increasing demand of energy overstepping its supply. We have always known that the energy we use everyday is not unlimited, yet we take it for granted. Oil, gas, power, even water has limited availability. Yet, we have not taken enough precautions to deal with a possible energy crisis. When I say ‘we’, I am not referring to the governments but to all of us, the common people.
Oil and gas have already become too expensive, and with each passing day, they are moving towards being extinct. Some ignorant people think that energy crisis is a myth. They fail to see the big picture. There have been three major energy crises so far – the 1973 oil crisis, the 1979 energy crisis, and the 1990 oil-price hike, apart from several regional crisis.
Prices have been rapidly increasing for the last five years, thanks to the ever-increasing demand and the increasing shortage of energy resources.
How soon will it be all gone?
Are the cynics right in saying that we are making a mountain of a molehill, or is the energy crisis for real? Picture this: We have already exhausted 50 percent of the available oil. At the current rate of consumption, the rest of the oil will finish in 32 years! Imagine if the rate of consumption increases! We all know it is bound to increase. So, even the present generation will face an acute energy crisis in the later years, let alone future generations.
What are we doing about it?
Are we equipped to face the impending energy crisis? What can you and I do to tackle it? For starters, we need to understand the importance of energy in our lives and stop taking it for granted. We have to minimize the use of oil, gas, electricity, or any other fuel. We cannot afford to waste any available energy. It is also important to spread awareness about limited availability of energy resources. Simple things like joining a car pool, switching off car engines at traffic lights, and minimizing the use of gas and oil in everyday activities will help a long way in crisis-readiness.
What are the alternate energy options?
As a responsible world citizen, start looking for alternate energy solutions like solar energy and wind energy. Employing these alternate power solutions is extremely feasible and cost-effective. You will not only cut down your power bills but also contribute to a better future of the world.

How Electricity is Produced
Electrical energy was one of man’s greatest discoveries. It has helped build new civilizations. The large amount of electricity produced has its source in fossil fuels, nuclear fission, water, and wind. This article will explore the different methods of electricity production.
Electricity is churned out by enormous turbines. These turbines need a support to be moved. There are various ways of moving these turbines:
By burning fossil fuels: Electricity is produced when the blades of a turbine are moved by enormous amounts of vapour. This vapour is generated by heating a lot of water in huge furnaces. The water is heated by burning fossil fuels like coal, petroleum, and natural gas. This method releases enormous amounts of carbon dioxide in the air, thus severely polluting our atmosphere. It is important to turn to alternate methods of electricity production for long-term benefits.
By water: You must have heard how dams are constructed to produce electricity. A popular method to produce electricity, a water dams serves two purposes: restricting water bodies and producing electricity. Water dams use the river water to move turbines, helping them produce electricity. Electricity generated this way helps control air pollution; however, this method of electricity production adversely affects the ecosystem in the water bodies.
Water accounts for 90 percent of the world’s electricity generated through renewable resources.
By wind: Electricity is produced when wind energy is converted to electrical energy. Wind mills or wind turbines are used to churn up enormous amounts of wind energy which is then converted into electrical energy.
The latest in wind energy advancement tells us that wind energy is helping create portable cell phone chargers.
By nuclear fission: Yes, nuclear fission does not only make atom bombs, but also helps produce electricity. Nuclear fission causes a chain reaction where the element Uranium is bombarded by neutrons causing it to split. Every time a Uranium nucleus is split, more neutrons are released, causing more splits in the already split Uranium nuclei. The resultant chain reaction generates a lot of heat which is used to heat water the vapour of which eventually moves turbines to create electricity.
By bio-waste: With technological advancements, electricity is also being produced by bio-waste. Bio-gas is a typical way of generating electricity in rural areas in countries like India. In fact, a new technology evolved in the state of Bihar in India that uses human waste to generate electricity.
