#the clean energy revolution
Using clean, renewable energy is one of the most important actions we should take to reduce the impact of effects caused by climate change to the environment. Some of the clean energies include hydropower, wind power, solar energy, geothermal energy and bio energy. Electricity production is our number one source of greenhouse gases, more than all of our driving and flying combined and clean energy reduces harmful smog, toxic buildups in our air and water, and the impacts caused by coal mining and gas extraction. Clean energy also means biomass to bio gas (cow manure, crop stubble or any organic material), bio fuels used in heating and to run engines. Clean energy means clean water, a solar pump brings water to the village and saves women and children hours otherwise would be spent walking. Clean energy means clean sanitation, In waste digesters biogas can be captured for useable cooking fuel.
Clean energy is essential for healthcare, lights for surgeries and procedures, refrigeration facilities for medicines for natal vaccines, treatment of wounds and drugs crucial for fighting malaria and AIDS. Clean energy makes communication possible, solar powered cellphones keep people connected with their loved ones and finally clean energy provides adequate solar powered lighting to homes, schools, universities, hospitals etc.
Meanwhile Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas. Other commonly used derivatives include kerosene and propane. Fossil fuels range from volatile materials with low carbon: hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. Methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates. The Energy Information Administration estimated that in 2007 the primary sources of energy consisted of petroleum 36.0%, coal 27.4%, and natural gas 23.0%, amounting to an 86.4% share for fossil fuels in primary energy consumption in the world. Non-fossil sources in 2006 included nuclear 8.5%, hydroelectric 6.3%, and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%. World energy consumption was growing about 2.3% per year. We understand that the wide scale use of fossil fuels, coal at first and petroleum later, to fire steam engines enabled the Industrial Revolution. At the same time, gas lights using natural gas or coal gas were coming into wide use. The invention of the internal combustion engine and its use in automobiles and trucks greatly increased the demand for gasoline and diesel oil, both made from fossil fuels. Other forms of transportation, railways and aircraft, also required fossil fuels. The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry.
The use of fossil fuels raises serious environmental concerns. The burning of fossil fuels produces around 21.3 billion tonnes (21.3 gigatonnes) of carbon dioxide (CO2) per year, but it is estimated that natural processes can only absorb about half of that amount, so there is a net increase of 10.65 billion tonnes of atmospheric carbon dioxide per year (one tonne of atmospheric carbon is equivalent to 44/12 or 3.7 tonnes of carbon dioxide). Carbon dioxide is one of the greenhouse gases that enhances radiative forcing and contributes to global warming, causing the average surface temperature of the Earth to rise in response, which the vast majority of climate scientists agree will cause major adverse effects. A global movement towards the generation of renewable energy is therefore under way to help reduce global greenhouse gas emissions. First and foremost we need to ensure energy efficiency as a key step to reducing our impact on climate change and creating a sustainable energy future because every time you flip on a light switch, use your computer, take a hot shower, or turn on your heater, you’re using energy. Research indicates that average U.S. home uses about 11,000 kWh per year, and a large portion of that energy is wasted and therefore by using less energy without sacrificing comfort, you can save money while helping the planet; Use energy efficient lighting, like compact florescent (CFL) or LED light bulbs in our homes and workplaces, turn down our water heaters to the warm setting, unplug your cell phone and laptop chargers when you’re not using them, use the energy-savings settings on the appliances you have and buy Energy Star–labeled appliances when you replace them and replace the filters in your furnace and air conditioner. We also appreciate efforts done by the United Nations climate change/environmental bodies and other small or big non-governmental organizations that are at the forefront of fighting for cleaner/renewable sources of energy and most importantly with the signing of the Paris agreement two years ago. The clean energy revolution is therefore unstoppable either with the biggest economy with us or not, Nations around the world are determined to ensure zero emissions by 2050. It is therefore important that the bigger polluters do ensure that by 2030 to have established incentives to use 80% renewable energy, for electricity, transport, or even total primary energy supply and the poor countries setting their targets to 20% renewable energy supply as we forward to ensure 100% renewable energy total energy supply by 2050.
