Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Solar energy is inexhaustible. Noise free.
technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels when they break through to the industrial scale. 2. The scale of biofuels production 2.1. Drivers of biofuels production Lal (2010) stated that "three inter-connected challenges face humankind in the 21st century": food security, climate change, and energy security. The world population is projected to reach 9 billion in 2050, posing more demands on energy, food, and other natural resources. It has been estimated that the world food production needs to double and meat production increase by 85% by 2050 to fulfill projected demand by population (Karp, 2011). In the recent decades, the food consumption in the most populous counties has shifted from grain-based diets to meat and dairy diets. Meat production requires times more biomass in the form of

Introduction To be honest I got the list of topics after most interesting ones for me were taken. At first I was not very satisfied with my topic but then I realized that this could be actually really interesting thing to make a report of. I chose this particular topic because I have always been interested in green energy. This topic gave me an excellent opportunity to improve my knowledge about these kinds of things. For me this report is a great challenge because I have not done anything like this before, especially in English. Primary goal for me is to improve my knowledge about renewable energy and also usage of English language. This report is going to talk about biogas. It provides a brief review of usage and future prospects of the biogas. I have tried to make this report as understandable as
decimating. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life. FIND OUT 5 WAYS HOW TO HALT THE LOSS OF BIODIVERSITY 6. Deforestation: Our forests produce fresh oxygen and help in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and making that land available for residential, industrial or commercial purpose. FIND OUT 5 WAYS HOW TO STOP DEFORESTATION. 7. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton. Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be
Renewable resources: Some natural resources can be reproduced within a few years or decades. These are called renewable resources. Solar radiation, wind and hydroelectricity, are perpetual resources that are in no danger of a lack of long-term availability. Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be carefully managed to avoid exceeding the worlds capability to displace them. Solar energy is the energy derived directly from the Sun. Along with nuclear energy, it is the most important source of energy on Earth. People usually use solar energy to produce electricity and heat. Wind power is the conversion of wind energy into a useful form of energy, such as electricity, using wind turbines. These wind turbines are popular in counties, where the average speed of the wind is at least 6 meters per second for example in Germany, Denmark, USA and India.
