Water and energy resources

We use water and energy a gigantic amount of times during the day: for cooking, brushing teeth, heating/cooling, television....

Energy...

Energy consumption is expected to double by 2030. There are 1,5 billion people that still lack access to electricity. Today, most energy production is based on fossil fuels-coal, oil and gas but these energies are non-renewable and pollute our environment as they produce CO2 and greenhouse gas. To reduce costs and minimise the negative impacts, countries are creating energy saving and energy efficienty policies.

Water...

Freshwater represents about 3% of the water on Earth yet this amount is unevenly distributed on Earth resulting in water shortages in some areas where the climate is hot and the population is growing.

However, there can be water issues even in wealthy countries though water related challenges mostly happen in underdeveloped countries where they don’t have money to invest in infrastructure , in countries with hot climate and in countries where the water in contaminated.

At the global level, agriculture consumes a lot of water.

A retenir :

-The global demand for energy has greatly increased since the 19th century because of population growth, an increase in the standard of living and changes in the way people live. -Energy consumption reveals development inequalities. -Energy resources are not endless. -We need to think about our future energy choices: vehicles that use clear energy, water/wind/solar/geothermal energy use even though their energy production is small today, using better materials in buildings. -Water is a resource that is unevenly available and an important part of the global population still lacks access to it which leads to serious health problems in developing and poor countries. -Different countries have different ways of accessing water resources.
