The world’s energy requirements can be reduced if individuals and organizations act to save energy and begin concentrating on renewable energy resources. Renewable energy is defined as a source of energy coming from natural resources refilled such as the wind, tides, waves, sunlight, and geothermal heat, etc. Renewable energy resources are used to replace popular fuels in four common areas: air and water cooling/heating, electricity generation, rural energy services and transport fuels. In 2013, renewable hydroelectric energy accounted for 16.3% total electricity production in the world and when this energy resource was combined with other common renewable energy resources such as solar, the wind, geothermal, etc., they made the total renewable energy, 21.7% of electricity production worldwide. Solar water heating contributes a huge amount to renewable heat in some countries. For example, in China, these systems are mostly installed on apartment buildings in order to meet a part of the hot water requirements of approximately 50-60 million households. In transport fuels area, renewable bio-fuels made a contribution to a decline in oil consumption. According to a survey, in 2009, 93 billion liters of bio-fuels worldwide replaced nearly 68 billion liters of gasoline, which is equivalent to 5% of gasoline production worldwide.
10 Common Renewable Energy Resources:
There are many renewable and environmentally friendly energy resources. They can not be exhausted and are constantly renewed. They provide an alternately clean source of energy, contributing to reduce the bad effects of definite forms of pollution. Using renewable energy resources does not create air pollution or greenhouse gas emissions. On a single level, using them will reduce the carbon footprint.
In the article today, I would like to reveal some of the common renewable energy resources in details so you should keep your head on the following interesting lifestyle facts and the list of renewable energy resources. They include:
This is the first out of common renewable energy resources that I would like to introduce in this entire article and want you and my other readers to learn and make use for good!
Solar energy, the heat from the sun and radiant light can be converted into electricity. With a rapid pace, solar energy is one of the fastest developing renewable energy resources.Solar technologies are defined as either active solar or passive solar according to the way they convert, capture and distribute solar power. Passive solar technologies orientate a building to the sun, choosing materials with favorable light dispersing properties and thermal mass, simultaneously designing spaces for naturally circulating air. Active solar technologies include solar thermal energy, utilizing solar collectors for water heating.Solar cells are getting more transportable, efficient, and flexible so we can easily install them than before. Solar energy is mainly used to provide power for small and medium appliances. People can harness solar energy during the day if the sunlight is not prevented by buildings, clouds and other obstacles. Now, there are two solar technologies that involves in electrical equipment. First, solar photovoltaic technology utilizes cells to turn sunlight directly into electricity. Second, solar panels or collectors are used to use ventilation air in buildings or to heat water.
The development of clean and inexhaustible solar energy technologies will bring huge everlasting benefits. It will help increase energy security of each country relying on an inexhaustible and independent resource, reduce pollution, lower the risk of climate change and global warming, and increase the sustainable growth and lower fossil fuel prices. Solar power permits consumers to be self-sufficient to their own energy supply, which is good for single consumers as well as goof for the whole society. However, the cost of solar panels is higher than other forms of energy. The cost of installation and maintenance of solar power can be costly. And the sunlight is can be blocked by some factors, so there is need to hold electricity in storage cell to cover days with little or no sunshine.
Solar power is actually an effective renewable energy resource for the future, so try it out!
Wave power is a kind of transport of energy from ocean surface waves for useful works such as water desalination, electricity generation, and water pumping. This renewable energy resource can be difficult to control because of the unpredictability of wave direction as well as the ocean. Most of the wave power systems create energy by movement coming from the wave troughs and peaks or by a snaking motion.
Wave power is ideal for an island. It is also a clean and abundant energy. However, it also has some disadvantages. It prefers operating in small local areas rather than done on a national scale. The cost of the installation and maintenance of wave power facilities is costly. Additionally, some local and environmental groups also reject this energy object.
This is, in fact, one of the common renewable energy resources that people should learn and make use to contribute to energy supplies.
The atmosphere’s movement is caused by the difference in temperature at the surface of the Earth. Wind power is a kind of conversion of the source of wind by using wind turbines to create useful forms such as mechanical energy or electricity. When wind speed increases, power output also increases up to the maximum rate output. Places where winds are strong and constant such as high altitude sites and offshore are suitable to build wind farms. The local electricity transmission network is connected to large-scale wind farms to supply electricity to certain areas. Wind turbines installed on grazing areas or agricultural land, have low environmental impacts. In the history, wind energy was used directly for propelling sailing ships, pumping water, and grinding grain, but today, the main use of wind energy is to generate electricity. The long-term potential of this renewable energy resource is estimated to be five times total world energy production in the present, or 40 times electricity requirement in the present. In order to get this target, wind turbines need to be installed in larger areas, especially in places of a higher source of the wind like offshore. Average offshore wind speed is much greater than that speed of land, so offshore wind resources can make a large contribution to wind power production.
With wind energy, Consumers and societies can make benefits from wind energy. The OEERE shows that wind power is among the most effective of all of the renewable energy resources. It is described as a clean and good energy source for our environment and for our health as it does not give off air pollutants. However, we need to concern about the long-term effects of the turbines on the habitat. Some locals reject on-shore wind farms as it can spoil the countryside. Wind turbines are large and you can make use of the area under them for other purposes, but they are unattractive looking. They also make noise when operating. In addition, they can put the wild bird population at risks.
In fact, this is also on the list of renewable energy resources so that people should make use of this source of energy to produce more electricity.
Tidal energy can be produced in two ways: by barrage generation and by tidal stream generators. The power generated by tidal stream generators is environmentally friendly as it causes less bad effects on established ecosystems. Like a wind turbine, most of the tidal stream generators alternate underwater and is propelled by the quickly moving dense water. Although it is not widely used, tidal energy still has a large potential to generate electricity in the future. This is because we can predict tides more easily than solar energy and wind energy. In the history, tide mills were used in both Europe and on the USA’s Atlantic coast from the Middle Ages. Besides, tidal energy is the only energy form which extracts directly from the motions of the Earth-Moon systems.
Tidal power is ideal for an island country and tidal barrage can help prevent flooding. Besides, in the future, underwater turbines can be out at sea and tidal power does not need dams. However, tidal power has some drawbacks. Firstly, it is very costly to construct a barrage. Secondly, only some estuaries are suitable to build tidal power facility. Next, some environmental groups object to this energy project as it has the negative effect on the wildlife. Finally, using tidal power can lead to a decrease in tidal flow and flow of sewage out to sea.
This is, in brief, one of the common renewable energy resources for the future so that people should not look down it.

Another out of the list of renewable energy resources that I would like to reveal in this entire article and want you and my other readers to learn and know the role of hydropower in producing electricity.
This form of energy uses the gravitational potentiality of flowing or falling water to create power. It is the most popularly used form of renewable energy resource. There are some common forms of hydropower: hydroelectric energy which is reserved for extensive hydroelectric dams, micro hydro systems which are used in water rich places as a RAPS (remote area power supply) and run-of-the-river hydropower systems which derive power from rivers without creating a large reservoir. Micro hydro power has become an increasingly common renewable energy source, especially in areas where other energy resources are not available. Small-scaled hydropower systems may be able to be installed in small streams or rivers with no disruption to fish immigration. Most of these systems do not make use of a major water diversion or a dam, but rather get water wheels to produce power. This accounted for approximately 63% of power from renewable resources. While many of hydropower projects provide public electricity networks, some of them are used to serve specific industrial areas. Early usages of this renewable energy resource consisted of mechanical power for transformation purposes such as sawing, milling, and irrigation and for transportation purposes such as removing logs. The amount of energy produced from water depends on the water’s speed and its volume. In order to take advantage of water’s speed, people usually build a hydroelectric station at a waterfall or a sharp incline, while dams are usually built at somewhere to regulate the water flow.
Hydropower is clean, abundant and safe. It also gives recreational benefits such as fishing and boating. Strictly speaking, it is not a renewable energy resource, if you want to fill up all reservoirs to become useful again, you need very expensive excavation. Besides, it can cause some environmental and social impacts, and as a result, some people can lose their homes due to floods.
This renewable energy resource is a very powerful way and is from thermal energy created in the Earth. The geothermal energy comes from the absorption of solar power deep within the Earth and minerals’ natural decaying in the ground. The geothermal acclivity due to the difference in temperature between the surface of the planet and its core, leads to a continued conduction of thermal power. The heat used for geothermal power can be from Earth’s core to 6,400 km down. At the core, the temperature can be up to 5,000 oC. Extremely high temperature conducting from the core and pressure make some surrounding rock melt, which is called magma. Geothermal energy is used for bathing, space heating and electricity generation. This can be used on a small scale to supply heat for a residential area or on a large scale for producing energy via a geothermal power plant. Geothermal power gives a level of scalability: a large power plant can provide power to entire cities, and small geothermal power plant can provide power to some rural villages or individual homes.
This power is effective, environmentally friendly and even reliable, but it is limited to some locations of volcanic areas and is also limited by many other technical problems. Geothermal power does not need fuel and, therefore, lower fuel cost, but its capital costs are quite high. Drilling accounts for most costs of electrical plants, and the exploration of deeper resources needs the high costs. Along with the heat, geothermal energy can also bring toxic chemicals when using the steam.
This is actually also one out on the list of renewable energy resources that a lot of people love and have been making use of it to heat and create the electricity in their everyday life without meeting difficulties.
This is also one of the common renewable energy resources that people should learn and make use as soon as possible for good.
Strictly speaking, they are also not renewable energy resources, but they are very available and are not pollutants when be used. Similar to a fuel, hydrogen can be burned with just water as the burning product. This burning fuel is clean, that means using it can significantly reduce pollution in cities. Otherwise, hydrogen may be able to be used in fuel cells, which are like batteries, to provide power to an electric motor. In this case, the production of hydrogen needs abundant power. Because of the energy requirement to generate the initial hydrogen gas, the result of this production is the relocation of pollution.
There are some disadvantages when using hydroelectric power. Firstly, hydro generators require rain to fill dams to provide flowing water. Secondly, rivers have to be dammed, which have some negative impacts on the wildlife and land. Next, the cost to build dams is so huge while the return is slow.
Another one on the list of renewable energy resources that I would like to reveal in the entire today and want you and my other readers to learn and consider making use of this power in your daily life.
Biomass is biological material extracted from living. Energy in this renewable resource is very widely used in the world. It often refers to plant-derived materials and plants such as wood, food crops, grasses, agricultural waste, etc. which are called lingo-cellulosic biomass.Biomass has become a vital source of energy since people began burning wood to warm themselves in the winter and cook food. Today, biomass can be used directly through combustion to create heat or used indirectly after transforming it into other forms of bio-fuel. People can make a conversion of biomass to bio-fuel by some different methods which are divided into: chemical, biochemical and thermal methods.
Using biomass can cut down on the space for landfills while permitting existing landfills to last for longer. Biomass is really available, cheap and long-term source of energy. In some instances, biomass is used with two goals: produces energy and solve waste products. Biomass, bio-fuels, and biogas are burned to generate heat, so they are harming the environment. The huge amount of pollutants such as Sox, NOx and PM are produced from the burning of biomass, and this process is the main contributor to air pollution in many areas. Finally, it is a renewable energy resource only when crops are replanted.
In fact, this is among the most common renewable energy resources so that people should pay attention to make use of it for good!
This renewable energy can make the same wonders as public electricity with less cost. It does not act exactly like electricity, but it has contributed to its scientific community‘s misunderstanding. This energy form may be able to be collected directly from the environment or derived from the electricity by fractionation method.
This is also a great one on the list of renewable energy resources for the future that people should not look down but learn and consider taking advantages of this source of energy to create the electricity.
This is the last but very important out of the list of renewable energy resources that I would like to reveal in this entire article and want all of my readers to know the importance of nuclear power in producing electricity.
Nuclear power is nuclear technology designed to turn atomic nuclei into usable energy through controlled nuclear reactions. Nuclear power is a source of sustainable energy that can make a reduction in carbon emissions and an increase in energy security by reducing dependence on foreign oil. Some people think that nuclear power is a dangerous energy source so there is need to decrease the proportion of nuclear energy, and others think that thanks to new technology, the risks may be able to be reduced.
Renewable energy resources are sustainable and they will never run out. Their facilities require less maintenance than ordinary generators. Their fuels are extracted from available and natural sources, leading to the reduction in the costs of operation. More importantly, these energy resources produce little or even no pollutants, so they have minimal effect on the environment. Besides, these energy projects may be able to bring economic benefits to some of the regional areas from the increased tourism and local services. Investing in these renewable energy resources can create more jobs in everything from manufacturing to installation so many individuals can take advantages of new job opportunities. Although we can see the advantages of renewable energy resources, we also need to be aware of their disadvantages. Firstly, generating the huge amount of electricity with renewable energy is more difficult than those produced by ordinary fossil fuel generators. This means that we have to reduce our energy requirements, or build more renewable energy facilities. Secondly, the reliability of supply is also a problem. These energies often base on the weather for the source of power of it. As these resources are not available, the ability to make energy can be inconsistent and unpredictable. Next, the cost of these energy technologies is more expensive than ordinary fossil fuel generators, so they do not attract many of single households.
