Renewable energy

Negative aspects of solar energy Solar energy does not work at night without a storage device such as a battery. Cloudy weather can make the technology unreliable during the day. Solar technologies are very expensive. Requires a lot of land area to collect the sun's energy. Wind energy Most wind energy comes from wind turbines. Wind turbines are used to wring electricity from the breeze. Wind turbine use has increased at more than 25 percent a year. Wind is a clean source of renewable energy that produces no air or water pollution. Wind is free, operational costs are nearly zero once a turbine is erected. Negative aspects of wind energy Wind turbines make noise. Slowly rotating blades can kill birds and bats. Wind is variable: if it's not blowing , there's no electricity generated. Wind turbines are expensive. Hydroelectric power Hydropower is electricity generated using the energy of moving water. Hydropower is the cheapest way to generate electricity today.

Environment and renewable energy

Environment and renewable energy 1. How can we help bring about a change in behavior? * Renewable energy is the sun and the water that people use, but not yet so widely. Required on all homes, various stations, hypermarkets solar panels to use the potential energy, the stock of which is not completed within 5 billion years. * Renewable sources such as wind and solar are intrinsically unsuited to meeting the demand for continuous, reliable supply on a large scale – which comprises most demand in developed countries. The criteria for any acceptable energy supply will continue to be

Wave-energy

complicating the estimation of the output. Additionally every type of device will react differently to varying wave climates. Therefore the predictability of power output from a certain sea state must be separately improved for each WEC. Ther is a huge challange for material properties due to a high number of cycles over the livetime and the corrosive atmosphere. In general the current costs of wave energy are higher than those of more mature offshore renewable energy sources, e.g. offshore wind turbines. In order to enhance the affordability of wave energy innovation is needed. Future wave energy converters will be geared towards cost reduction. In long-term view the affordability of a device will identify the economics of a project and not the huge capital expense, that is needed for a demonstration project [Muel2015]. 24 In general the current costs of wave energy are higher than those of more mature offshore renewable energy sources, e.g

Green Energy presentation

have reworked policies to promote growth that is more environmentally sustainable Germany's policies aimed at "greening" the economy provide several lessons for the United States about how to make sustainability politically acceptable in a federal system of government Germany's impressive feat has been less about innovation than about implementation Germany has become a forerunner in promoting a greener, more sustainable future German Renewable Energy Act (Erneuerbare-Energien-Gesetz (EEG)) · The Act came into force in the year 2000 · Initial spark of a tremendous boost of renewable energies in Germany · Proved to be the world's most effective policy framework at accelerating the deployment of renewable energy technologies · The Renewable Energy Act was the central political element of one of the greatest paradigm shifts since the start of the industrial revolution:

Biogas – The source of future energy

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 possible. By the end of this report I want to come to a conclusion whether biogas is the best source of future energy or are there any other sources that are better. What is biogas? Typically it refers to the gas produced by the anaerobic digestion or fermentation of
