Alternative energy is energy that is used to support the use of conventional energy. It is referred to as alternative energy because it is a backup energy for existing conventional energy.

One form of alternative energy is solar energy which can be used to generate electricity with the help of solar panel technology .

This discussion will explain the advantages and disadvantages of using alternative energy. Here is the explanation.

Alternative Energy Advantage

1. Alternative Energy as Renewable Energy

The advantage of the first use of alternative energy is that it never runs out because it is included in renewable energy. Meanwhile, fossil energy, coal, oil, and other conventional energy will run out in about 100 years. The latest technology has indeed succeeded in showing fossil energy sources that have never been found.

However, this energy will also remain depleted when used continuously and by many people. This is where the important role of renewable alternative energy because it will never run out. As long as there is still a shining sun on earth, humans can use it using solar panels.

The changing temperature of the sun will also trigger the wind, so it can be used for wind energy. Likewise with the availability of abundant water on earth. Explaining the advantages and disadvantages of using alternative energy cannot be separated from its presence which is very important to support energy use.

2. Free Energy Source

Another advantage of using alternative energy is that it does not cost money to buy it because it can be obtained for free. An example is sunlight which is used as an energy source for solar panels, you don’t need to buy it because it is available in abundance. The costs required are the initial costs for installation and preparation.

The rest of this alternative energy can run by itself without the need to pay for re-purchase. This is of course different from the price of coal or oil which tends to always rise and requires a fee to make repeat purchases. Therefore, there are some people who choose to take full advantage of alternative energy.

3. Environmentally Friendly

The discussion that explains the advantages and disadvantages of using alternative energy certainly cannot be separated from the advantages of being environmentally friendly. The use of alternative energy does not produce harmful gases or other processes that can damage the environment. Utilization of wind energy does not produce any pollution that affects the environment.

Likewise with the use of solar energy and water energy, although the results are not as clean as wind energy. They all do not produce carbon emissions which are feared to be the main cause of environmental damage on earth. In contrast to fuel oil which produces a lot of harmful gases and can cause air pollution.

Alternative Energy Disadvantage

1 . Fairly High Initial Installation Cost

After knowing the three advantages of using alternative energy, now is the time to know the disadvantages of using alternative energy.

The first drawback of using alternative energy is the high initial installation cost. For example, when using water alternative energy, a dam must be made first.

This of course requires a lot of money and many things need to be prepared. But don’t worry, there is one alternative energy with an affordable investment cost.

You can use alternative energy solar power to supply electricity in your home. With the help of solar panel technology, you can get electricity at an affordable investment cost with SUN Energy.

SUN Energy is the largest solar panel developer in Indonesia, with a DP0%, now you can have solar panels from SUN Energy.

2 . There are still few users

Quoted based on the press release of the Minister of Energy and Mineral Resources “311.Pers/04/SJI/2020” that the current capacity (generating) of energy sources is 70.96 Gigawatt (GW). Of the total energy capacity, 35.36% of the energy comes from coal; 19.36% came from natural gas, 34.38% from oil and EBT (New and Renewable Energy) by 10.96%.

In fact, Indonesia is noted to have NRE resource potential of more than 400 Gigawatt (GW). This is a very large number compared to currently available energy sources. Of this total energy, only 2.5% of the alternative energy is utilized. And of course, over time the use of alternative energy will increase.

Closing

Alternative energy does have some advantages and disadvantages that are worth considering. One of the wise steps that can be taken is to continue to use it even though it is only 50 percent. You can use solar panel technology from SUN Energy to help reduce the use of electrical energy from conventional energy.…

Dewatering is one way to control water at a mine site. In the mining industry, dewatering is an important thing that needs to be done so that the mining process can run well.

Previously, controlling water at mining sites was basically divided into two types, namely:

• Mine Drainage : Efforts to prevent water from entering or flowing into the work area. Mine drainage is generally carried out to treat groundwater or water originating from surface water sources. For example, various methods of diverting surface water flow ( river diversion , making ditches, and others).
• Mine Dewatering : Is a way to remove water that has entered and is in the mine site. Mine dewatering is done by making a sump (delayed well), a trench system, and a pumping system.

Mine Pump for Dewatering

In the mining industry, mine pumps are indispensable and need to be known. This is because this tool is like a medium that guards the work location so that mining activities can run without obstacles.

Even in today’s era, every coal mining company is highly recommended to use mining pump services. This recommendation is intended so that the work can run effectively, efficiently, and with minimal risk.

Because, apart from dewatering, mine pumps can also be used to provide water to mining areas through river water that is used.

The mine pump itself has a working system with the principle of flowing water that is in a water reservoir or sump to the river so that the water does not interfere with the running of mining operations.

Types of Mining Pumps Dewatering

It should be understood, the water in the sump is water that comes from mining. Even so, this water is also a mixture of rainwater. For water from mining comes from each excavation which eventually releases groundwater.

The water is also collected in sump reservoirs and will later be channeled into the river.

In general, there are two types of mine pumps commonly found at mine sites. Here’s the review:

1. Non Submersible Mine Pumps

The type of non-submersible mine pump is a pump that is on a pontoon or land. This pump has a higher capacity because it can move water from a larger discharge.

Not only that, non-submersible mining pumps can also be driven using two types of power, namely electricity and diesel.

2. Submersible Mine Pump

Submersible mining pumps are the opposite of non-submersible pumps . Miners generally also need this type of pump to carry out dewatering . As the name suggests, this type of pump works by being immersed in water.

The power capacity available by these pumps is generally lower than that of non-submersible pumps . This pump works after excavation of the mine which produces water, then the flow is diverted.

Before draining water with this pump, it is necessary to ensure that the water must have a low PH, ranging from 3 to 5.

3. Electric and Hydraulic Submersible Pump

Submersible mining pump propulsion device , which is a tool with an electric type. For electric and hydraulic submersible pumps , the ends generally require different levels of immersion.

Meanwhile, power packs need a flat and wide space on the ground. Electric submersible pumps can handle large volumes or significant heads , but are limited to handling smaller solids at higher heads .

This type of pump must be installed semi-permanently, moved infrequently, and maintained by a qualified technician or electrician.

In most cases, electric submersible pumps (such as vertical turbines) run at very high speeds. Meanwhile, the required head can be achieved at a speed of approx. 3,600-rpm.

This creates potential wear from pumping slurry water at high speeds, reducing pump life. While the rubber coating on the wear parts may be a solution, it is not a long term solution compared to the hardened wear plates of these pumps.

4. Trash Pumps

Garbage pumps are usually portable and can handle solid water, making them ideal for dewatering applications . This type can also be run on diesel, gasoline, or electricity depending on your needs.

The garbage pump is designed with a deeper impeller vein and a larger discharge opening. This allows it to move liquids containing solids that would normally clog other standard pumps.

The garbage pump can even perform applications at higher speeds.

The main advantages of the sewage pump in dewatering applications are the adjustable speed and higher flow and discharge pressure.

This pump is also easy to use and maintain due to fewer components than other pumps.

Even so, the garbage pump also has its drawbacks, its fuel capacity is limited so it must be monitored and filled more often.

5. End-Suction Pump

This pump is the most common type of centrifugal pump and is widely available in a variety of sizes, …

The increasing demand for energy makes the use of renewable energy begin to be carried out. Renewable energy is the best option to meet the need for electrical energy considering that non-renewable energy such as fossil fuels and coal is predicted to run out and take thousands of years to be renewed.

Unfortunately, until now the use of renewable energy has not been maximized considering the various impacts caused by its use.

The following impacts need to be considered first so that the use of renewable energy can be profitable in the short and long term.

Renewable Energy  Social Impact

If considered in terms of its social impact, the use of renewable energy can provide social benefits such as an increase in a healthier environment, advances in technology and opportunities for work.

This can happen considering that some renewable energy resources such as water, wind and sunlight are considered environmentally friendly and can reduce pollution levels.

However, not all of them can maximize this potential, considering that renewable energy such as water, wind and sunlight are not obtained in equal portions in each region, so there is the potential for social inequality to occur.

Renewable Energy Economic Impact

Economically, the use of renewable resources can clearly have a big impact. This is because renewable energy development projects can increase employment opportunities, benefit material suppliers, and simultaneously revive the economy.

On the other hand, the use of renewable energy can also have a good impact in the long term because it is considered more cost efficient.

However, to realize the use of renewable energy requires a lot of investment and this often hinders the development of renewable energy.

Environmental Impact

One of the biggest impacts that will be felt in the use of renewable energy is the environmental impact. Some renewable energies such as sunlight, wind and water tend to be environmentally friendly and can reduce pollution in the form of carbon dioxide gas in the area around the plant.

However, to increase its capabilities, usually using batteries in solar PV storage. Waste batteries that are not used have the potential to become hazardous waste pollution. Therefore, it needs to be done together to recycle the battery.

Network Impact

In utilizing renewable energy, a different network is needed compared to the use of conventional energy. This is because renewable energies such as solar, hydro and wind are classified as unstable in terms of energy supply considering that their energy supply depends on climate and weather.

However, usually solar and wind power is off the grid, so for maximum utilization it is necessary to build a network that has the potential to increase costs.…

Solar panels are the conversion of sunlight into electricity, either directly by using photovoltaic, or indirectly by using concentrated solar power to produce electricity for your home or for your company.

Solar panels As a more efficient and more affordable solar power system to take advantage of the economic and environmental benefits . Solar panels are not just only used in homes , solar panels are used in the Region and outlying areas the location of the school that lacked electricity , people and equipment telecommunications and water pumps .

To get the most out of your solar panel system , it’s worth spending some time researching the solar power system to make sure you make the best decision when purchasing a solar panel system.

How Solar Panels Work

Solar panels function to bypass the photoelectric effect where certain materials create electricity when the sun shines on them . The solar panels themselves consist of silicon crystals in which each half is doped into a different dopant to produce a semiconductor . When the sun appears on the surface, the solar panels provide the energy needed for the semiconductor to generate direct current ( DC ).

DC / AC Inverter : This is needed to convert DC power , generated by the solar panel circuit , to AC power so that it can be used for electrical appliances at home as well as used by the power grid .

AC Circuit : is the main circuit into the house . It is connected to the fuse box and then the energy is used to power the appliances in the household . This AC circuit also connects the electricity meter to the house . This allows the utility company to determine how much power it buys from that household and how much power it supplies to that household .…
