Sustainable development is about management and development of our energy needs so that they meet the requirements of the present day without compromising the ability of our future generations to meet theirs. The scarcity of clean drinking water, energy, and arable land for food crops all have an impact on climate change as the dependency on fossil fuels increases. Sustainable consumption and production is about managing the worlds resources in a controlled and cleaner way.
Renewable energy sources are vast in scope and type from solar thermal and photovoltaic energy, hydro (tide, wave and ocean energy), wind power, geothermal energy as well as all forms of biomass products from biological wastes to liquid biofuels. Renewable sources of energy for home cooking, heating and transportation are becoming more widespread as our reliance on more traditional fossil fuels reduces. Renewable energy as a sustainable energy resource reduces greenhouse gas emissions with the development of energy from renewable sources increasing energy efficiency
Nonrenewable energy sources are those which took thousands of years to form and exist in fixed amounts in the Earth so cannot be replaced during the time of a humans life span. Norenewable need to be conserved before they become depleted. Fossil fuels in the form of coal, natural gas, and oil as well as fossilized wood, charcoal, and peat are all regarded as nonrenewable energy sources. Burning these fossil fuels accelerates global warming due to more greenhouse emissions and pollution released into the atmosphere
Renewable energy sources of energy are abundantly available around the world but are also insufficiently exploited to reduce our dependancy on harmful fossil fuels and increase energy capacity. Renewable energy technologies which harness the potential of the sun, sea, waves and thermal heat have the benefits of reducing the environmental and climate impact on life while at the same time providing a cost effective means of powering our homes and vehicles. The development of high-efficiency solar cells and modules, geothermal heat pumps and marine energy devices create an environment based on renewable sources that provide flexibility to the energy system
Renewable energy sources are sources of energy that are natural, continuous and largely available. Renewable energy sources are constant supplies of energy that do not run out as they are being continually replenished by mother nature such as the suns solar radiation. The popularity of renewable energy is well known as millions of people around the world use it to generate electricity, cool and heat their homes or to produce a variety of cleaner vehicle fuels. Renewable energy sources include the wind, water, oceans and geothermal with the move towards 100% renewable energy taking place around the world.
