Can Gravity Be Used As Renewable Energy?

Gravitational force is something that will exist even when man ceases to survive. So, can a man use gravity to generate energy without interfering with the environment? With the help of physics, most scientists and companies are already trying to solve this puzzle that has been around for a very long time now.

As early as 2014, the world believed that gravity could not be used as a source of energy. Some valid reasons were given. One of the reasons given is that gravity is a force and not the energy itself. That gravity only provides unidirectional energy exchange and transformation to different states for the objects.

A New Point Of View

However, researchers are coming up with gravity-powered electric generators and lighting systems in their quest to solve the puzzle.

In a video, a scientist demonstrates how mass and gravity can be used to produce electric power! He uses old clocks gearing and weights to turn a small homemade neodymium generator.

New Innovations

Innovative ideas have already been put into practice and we can see gravity being used as renewable energy.

In an idea to create a gravity-powered lamp, a model known as Gravia uses a simple weight on a ball screw to generate energy and power the lightbulb.

As the weight slides down the screw for more than four hours, the friction powers the lamb. However, a user has to physically bring the weight to the lamp after four hours.

In Switzerland, the Linthal Hydropower plant uses gravity to produce gravitational energy equal to a modern nuclear power plant. They use a simple concept here. When energy consumption increases, the release of the water and the high gravitational force causes water to flow through the huge turbines, generating electricity.

When the energy consumption decreases, the water is pumped back to the reservoirs until when consumption increases.

The power generated through this process is over 1450 megawatts, enough to serve over a million homes.

An Edinburgh-based energy company is also working on generating electricity from gravity.

With a lot of concrete, strong cables, and winding gear, high towers can be built or instead, find deep holes on the ground (like the mines).

The company plans to build a tower in Edinburgh to prove the concept of Graviticity-generating energy from gravity.

The company also wants to use mines that are closing to make use of the deep holes. The company is discussing this with mine owners in the UK, South Africa, Czech Republic, Finland, and Poland.

The company plans on using 24 weights, equalling 12,000 tonnes in the mine shafts. The weights could be released one by one or in combination, depending on the demand.

This apparatus is estimated to power over 63,000 homes every hour. The weights can then be recharged without any degradation.

Conclusion

It is clear that gravitational energy can have a great impact on man and the planet. If gravity is our future’s source of energy, then it holds more benefits towards attaining clean and renewable energy because gravity is not running out any time.

Trees

How Trees Add Value To The Energy Sector

Planting trees has always been encouraged majorly because of their massive contribution to the environment. But most people do not realize that trees can cause energy conservation.

 Planting the right tree in the right place is key to saving on energy. Here are ways how trees add value to the energy sector.

They provide shade, which saves energy

Trees are necessarily essential since they provide shade to their surrounding during hot weather. The shade reduces the cots of air conditioning for the home.

Plant deciduous trees that shed leaves during winter. They provide shade and block their surrounding from heat. Dropping leaves in fall allows for light to penetrate since it’s usually cold.

Plant these trees on both the south and west sides of the home. Ensure they are located in the right place to provide shade for all paved areas such as sidewalks, driveways, and patios.

Windbreakers to their surrounding 

Trees act as wind barriers during cold weather hence reducing the need for heating at home. Cold winter winds penetrate through small openings and drive away heat from the building.

Trees that act as windbreakers are characterized by canopies that extend towards the ground. Their branches should also keep foliage even in winter. These are the evergreens. Example trees that can perform this function are; evergreen shrubs, firs, spruces, Junipers, among others.

Wind barrier trees should be planted towards the north, northwest, and west sides of any building. They are grown in straight or curved rows. Additionally, plant them close enough so that their crowns meet.

Cool the environment

Trees are known to cool their surrounding by evapotranspiration or through shading.  But, trees also act as coolants by reflecting light and heat up to the environment than paved surfaces.

Trees along with the cool reflective roofs are essential in reducing the Urban Heat Island Effect. They again reduce the need for air conditioning.

Precautions:

  • Always plant trees some distance away from sidewalks and pavements to provide room for the canopy to develop.
  • Plant trees far from power lines’ location since their canopies may cause power surges and more maintenance costs.
  • Research the characteristics of a tree before planting them in your yard. That’s because some trees may form huge companies when mature and should therefore be grown at a specified distance from buildings.
  • To get the best energy-saving results, plant the tree in the right direction of the buildings.

Need an Expert?

All these processes may be overwhelming for anyone who is not a professional. However, considering an expert’s help may be the right solution to ease the burden and still enjoy your home’s energy conservation.

Imperial tree removal service is the best option. They will solve all your tree planting, removal, and maintenance needs.

Conclusion

Energy conservation is very vital in our lives. Look out for trees that help you save on energy costs and plant them around buildings. Also, growing trees will purify the air and act as coolants during hot conditions. They balance the temperature in places where they are planted.

Electricity usage

Need For Clean Energy In Today’s Cities

As the global electricity demand is expected to double by 2050, there is a need for cities to shift from fossil fuel consumption towards smarter energy sources. Technologies emerging are vital to help achieve this and help address environmental concerns.

The Transition

Cities consume up to two-thirds of the world’s total energy. This means they emit an equal amount of carbon. Modern cities are trying to develop new ways of energy consumption that support economic growth with less impact on the environment.

As a result, the energy system has been transitioning from a centralized model of power generation to a diverse network with several sources of power. Renewable energy sources have been added to the conventional grid to create an efficient and sustainable energy system called microgrids.

These technological energy systems can supply power in remote areas and also enables the storage of electricity in different institutions and buildings.

The Manchester Microgrid project

The of Manchester has been part of the Triangulum, the European Commission’s sustainable cities project. Manchester City Council, Manchester Metropolitan University, and Manchester University conducted an assessment of energy consumption and how to reduce costs and emissions by using renewable energy in the Oxford Corridor.

Microgrid systems were developed in the section of the city. It optimized energy consumption and reduced carbon emissions in the area. The city now avoids 57,000 tonnes of carbon emissions every year.

Espoo Smart Energy

A smart power in Finland’s second-largest shopping center has also been developed. A smart microgrid has been added to the shopping complex and connected to the energy system. It also enabled electricity storage through the smart battery system feature. Smart energy is designed to reduce the country’s need to invest in power plans. The shopping center now saves €125,000 every year on its annual electricity bills. It has also reduced carbon emission by 271 tonnes.

Challenges Of Getting To 100% Renewable Energy

Political Challenges

Lack of proper leadership politically can be a great challenge towards achieving 100% renewable energy transition. The city of Basel that has already transitioned to 100% renewable energy emphasizes leadership as an important factor in achieving clean energy. Basel says a clear vision is needed to engage with citizens and other stakeholders in the cities.

Technological Challenges

Providing clean energy in cities requires effective technology that will ensure the energy produced is enough to cover all the needs in the city. Most cities still do not have control over utilities making it hard for cities to work with them to shift to fully renewable energy. For instance, although Vancouver relies on 97% renewable power from an external utility, it cannot easily shift to 100% renewable energy.

Economic Challenges

With unsubsidized renewable energy being more cost-effective than fossil fuels, cities are investing in the sector. 570 cities are have valued renewable energy projects at $2.3 billion in 150 projects. This is part of a great shift to renewable energy that requires the development of more than 1,000 clean energy projects like electric transport and energy efficient=cy, which is worth more than $52 billion.

Save energy

How to save energy in commercial establishments?

Over the years energy consumption has been growing exponentially, becoming one of the largest expenses in commercial establishments. The increase in energy use has been a result of growing commercial office space, economic growth demanding more office space, and various energy-consuming devices.

The main energy consumers in commercial establishments include heating, cooling, and lighting. When you want to reduce expenses incurred on energy consumption, you have to start practicing effective energy-saving measures. Putting them into practice will ensure you maximize the use of energy and avoid wastage.

Here are some of the energy-saving measures which you can implement in commercial establishments;

HVAC Tune-up

In case your heating, ventilation, and air conditioning system (HVAC) have not undergone maintenance for long, it will not function properly. Besides, it would end up using more energy to achieve its target temperature. Therefore, ensure that you make a routine inspection, cleaning, and maintenance at least twice, before summer and before winter. This ensures full functionality and energy efficiency.

If you have had the same HVAC over years, consider upgrading it to a more energy-efficient and easier to maintain HVAC system.

Improve insulation to save plenty

Insulation is an easy way to save energy. Repairing any compromised insulation and adding insulation layers to your HVAC and electrical outlets helps to save energy.

Insulating your external wall also helps to improve energy efficiency as heat loss through the building is reduced.

Use of Energy efficient lighting

One of the largest energy-consuming systems in commercial establishments is lighting. Focusing on energy-efficient lighting can help cut down energy costs.

One of the energy-efficient lighting ways is using occupancy sensors to operate lights only when occupied. Also low consuming lights such as LED, fluorescent, Halogen, and HID.

Low-cost techniques

The use of low-cost techniques can significantly reduce your energy bills. Always ensure office electronic equipment like computers, photocopiers and printers are turned off when not in use.

Smart building

Smart building refers to buildings that have complete automated systems and controls in place. In smart building, sensors are integrated together forming an intelligent data collection application.

With smart building, you can check your HVAC performance, controlling its temperatures and transmitting commands via a centralized command system to change your settings and adjusting the values.  Hence, this is an effective way to save on energy.

Invest in energy-saving appliances

When exploring ways to save energy, never forget the use of energy-saving appliances. If your refrigerator, water cooler, and other devices use lots of electricity consider changing to EnergyStar rated appliances.

Establishing a work culture where finding ways to save energy is a priority to employees

Employees can be a great asset towards achieving energy saving costs goals. Where you have no automated systems in place always train your employees on energy conservation.  Employees should always put off their computers and lights before they leave. This always turns out to be a great energy-saving measure

Conclusion

Maintaining low energy consumption in commercial establishments can be difficult. However, with these tips, you will be able to cut down your energy bill and maximize on your profit.
