Alternative energy by Mind Map: Alternative energy

1. Alternative energy encompasses all those things that do not consume fossil fuel. They are widely available and environment friendly. They cause little or almost no pollution. There have been several alternative energy projects running in various countries to reduce our dependence on traditional fossil fuels. There are many impressive options that you can take into consideration such as solar tankless water heater reviews.

1.1. Solar Power

1.2. What better way is there to reach Type I status, than to get your energy straight from the source—solar power involves harnessing the power of our sun. From photovoltaic (PV) cells that capture photons and convert them into electricity, to solar thermal energy (STE) that makes use of the sun’s heat, solar is one of the most promising alternative energy sources on the market today.

1.3. Wind Power

1.4. For thousands of years, humans have harnessed the wind to push sails, mill grain, and pump water. Today, windmills use turbines to convert rotational energy into electricity that can reliably flow into to a grid. On a larger scale, wind farms are projected to provide as much as 20% of global electricity production by 2030.

1.5. Biomass

1.6. and biodiesel are among the most widely used renewable energy sources. In stark contrast to fossil fuels which are produced by geological processes that can take millions of years, biomass typically refers to biofuels that are obtained through biological processes such as agriculture and anaerobic digestion. Fuels like bioethanol from corn or biodiesel from transesterification of plant oils burn cleaner than conventional fossil fuels and can help countries stay within their carbon budgets.

1.7. Wind power is renewable source of energy and reduces our alliance on foreign countries for supply of oil and gas. It does not cause any air pollution and have created several jobs in last few decades. Advancement in technologies has brought down the cost of setting up wind power plant. Wind energy can only be used in areas which experience high winds which mean that it cannot be used as a source to extract energy anywhere on earth. They sometimes create noise disturbances and cannot be used near residential areas. These disadvantages have made the use of wind energy to particular regions only.

2. disadvantages

2.1. It is easy to recognise the environmental advantages of utilising the alternative and renewable forms of energy but we must also be aware of the disadvantages.

2.2. It can be difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. This may mean that we need to reduce the amount of energy we use or simply build more energy facilities. It also indicates that the best solution to our energy problems may be to have a balance of many different power sources.

2.3. Renewable energy often relies on the weather for its source of power and this can impact the reliability of a consistent energy supply. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors require clear skies and sunshine to collect heat and make electricity. When these resources are unavailable so is the capacity to make energy from

4. advantages

4.1. One major advantage of renewable energy is that it is sustainable and will never run out. They provide clean energy because they are non-pollutant and non-contributor to greenhouse effects and global warming.

4.2. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation.

4.3. Renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so have a minimal impact on the environment. Unlike coal, renewable energy pays off its carbon footprint and does so relatively quickly. Depending on where they are made, solar panels offset their carbon footprint in about four years.
