    Introduction 
    As a country, we have demanded more and more energy. But we have not brought on line supplies needed to meet that demand...We can explore for energy, we can produce energy and use it, and we can do so with a decent regard for the natural environment.
Energy is ability so do work. Energy comes from different sources such as oil, cola, wind, the sun, water, natural gas. Renewable energy is a source of energy that can never be exhausted. We can obtain renewable energy  from the  sun(solar energy), from the water(hydropower), from the wind(windmills), from hot dry rocks, magma, hot water springs(geothermal) and even from firewood, crop residues and waste(biomass).

RISING DEMAND
Electricity is a necessary part of our households. Energy demand has almost doublet in the last three decades. It is set to increase by fifty percent by 2030 and could double or even triple by 2050. The demand for gas has increased most rapidly, doubling between 1980 and 2004.

 
ECONOMIC GROWTH
Economic growth lifts people out of poverty giving them access to basic services like electricity, sanitation, clean water and mobility. As countries industrialize they need to build roads and railways and develop basic industries such as steel which are heavy energy users.
This is reducing poverty but also means consumption of more materials and more energy
.

WHY SHOULD WE CARE?
The energy market is global, so it doesn’t matter where the increased demand comes from. There is obviously potential for conflict as governments move to secure energy supplies in the face of competition for dwindling resources.
Climate change is also a problem for everyone. Energy produced from fossil fuels produces greenhouse gases which are contributing to the planet s rising temperature, bringing floods, higher sea levels and other increasingly serious consequences.

ENERGY RESERVES: HOW MUCH OI.L, GAS AND COAL ARE LEFT?
For example, currently about 60-70% of the oil in most fields remain unexploited in the ground because it has become too expensive to pump out as reserves have depleted. That s one reason why there is so much disagreement about how much oil and gas there is left. According to the International Energy Agency, oil production will peak and start to
decline some time in the next thirty years. Burning coal can produce severe local pollution as well as the carbon dioxide that contributes to climate change.
