Prior to industrialization the main source of energy as was sunlight, other forms of energy were wood, straw, dried cow dung etc. and these resources were infinite (Union of Concerned Scientists; 2017). For transportation muscle energy of horses was used, in the sea wind was used on sails to drive ships also water and wind was utilized to drive simple machines i.e. to pump underground water. Union of Concerned Scientists (2017) further stipulates that simple machines with power to harness steam were
Renewable Energy Faldu Smeet (16PGCL005) Renewable energy is energy which is generated from natural process and are continuously available. This includes sunlight, geothermal heat, wind, tides, water and biomasses. Renewable energy can be called as a green energy like as an example of sunlight, which is used for electricity, cooking purposes and it has variety of uses in industry as well as commercial. Renewable energy is money saving because it’s like one-time investment. To build stronger economy
fastest growing energy source in the world (“Cost of Wind Energy in the U.S”). Many controversies are occurring today in our society about whether the benefits of wind turbines outweigh the cons. Although some disadvantages come with having wind turbines, it is quite clear that there are more advantages with having a society with them. Wind turbines forming wind farms are cost efficient, a great source of energy, and a clean fuel source (“Advantages and Challenges of Wind Energy”). One tremendous
becoming worse day by day. The consumption of energy is increasing, limited resources of fossil fuel and their cost is increasing the requirement of renewable energy sources. This resources are basically a part of Earth's natural environment .This are obtained from natural resources such as wind, biomass, sunlight, green energy, tides, and geothermal energy. Electricity generation is one of their important application. Renewable energy such as solar energy is obtained from sunlight and has various applications
Brazil is the ninth largest energy consumer in the world. 41 percent of energy production of Brazil originates from renewable sources. One of Brazil's largest source of renewable energy is the Sugarcane plantation. The hydroelectric plant also is a big source of energy. Because of the recent, droughts, there is less Hydroelectric power being produced. The total energy consumption in 2015 was 13.6 quadrillion. The largest share of energy consumption in Brazil comes from the oil and hydroelectricity
Energy is a crucial component in our daily lives. It can be classified into renewable and non-renewable energy. Currently, non-renewable energy such as coal, oil and natural gas are the main consumptions in industries, transportation and power generation (International Energy Agency [IEA], 2015). However, there are adverse effects due to combustion of fuels such as air pollution and global warming. According to IEA (2015), worldwide carbon dioxide emission due to fuel combustion in 2013 is more
process; hydrogen energy will continue to be too expensive for most people. 2. Storage and movement is difficult. Hydrogen is hard to move around and transport as it is gas that must be stored without being contaminated (react with other elements) as it will cost even more to separate the compound or molecules again. Oil on the other hand can be transported through pipelines and coal can be carried in dump trucks and other heavy vehicles (Future, 2009). 3. Another disadvantage would be the
2. Why Choose Microalgae culture or Microalgae as an Ideal biomass? Or Microalgae: advantages and disadvantages The microalgae culture have the infinite potential to be used as primary producers of biomass in coming years, eventually they will turn out to be as most significant energy source. They can act as feedstock for several types of renewable fuels such as ethanol, methanol, biodiesel, methane and hydrogen. Table 1 represents certain feedstocks used for biofuel production (Chisti 2007; Dominguez-Faus
Biofuel is a fuel derived from biological material or the waste that living things produced. They serve as a renewable alternative to fossil fuels in the transport department , by reducing greenhouse gas emissions.(source: ec.europa.eu). The two most common types of biofuels in use today are ethanol and biodiesel. Ethanol is most commonly made by a process known as fermentation from biomass high in carbohydrates, sugars and starches. Ethanol is mostly used as a blending agent with gasoline to increase
expanded the horizons of science and technology. One of the advancements in energy production is the use of renewable sources such as solar, wind and geothermal energy. In the Philippines, the practical use of solar power through net metering and Peak / Off-Peak programs of MERALCO has been introduced in the Philippine household. The first solar cell came to life and it was the brainchild of Charles Fritts that has 1 to 2% energy conversion rate. Solar cells are dependent on photoelectric effect which
