Renewable energy is growing at a meteoric pace. Several countries have committed to 100% renewable energy targets that fall within the next two to three decades, with wind and solar energy as especially significant sources of the renewable revolution.

However, renewable energy sources have unique challenges that must be overcome before they can truly replace the classic electricity generation methods that we’ve been using over a century.

Grid energy storage

One of these is the simple problem of availability – solar, for example, is only available when the sun is out. When the energy source is unavailable, no electricity can be generated.

Grid energy storage was developed to address overproduction of electricity during off-peak hours, especially for baseload power plants such as nuclear power plants whose energy output is relatively inflexible. However, it has been co-opted to help solve the availability issue of renewable energy by storing energy during periods of generation, and releasing it when the source is unavailable.

Solar energy sector is the fastest growing renewable energy sector worldwide. It has been estimated that the global solar energy market could grow by 25% in 2019.

In U.S. alone, solar power is expected to provide more than 30% of all new U.S. electric capacity.

China, the world's largest solar energy market with the total installation of 45 GW at the end of 2018, is expected to experience growth of PV installations by 2%, even despite the uncertainties of the new solar support scheme which is yet to be announced.

Climate change is a huge issue in contemporary society.  The issue poses many problems, including how can businesses thrive in the modern world and still be green and sustainable.

For businesses, energy usage is a major factor, and many operations are seeking to become more fuel-efficient to reduce their carbon emissions, as well as bringing down costs.

Nowhere is this debate more prominent than in the 16% of the UK not serviced by the main gas grid, which relies on alternative fuels to meet its energy needs. For the majority of off-grid operations, this means a choice between oil, LPG (liquefied petroleum gas) or LNG (liquefied natural gas) for high-volume commercial applications. But what exactly are the differences between these fuels – and what should off-grid users consider when making decisions about their energy supply?

In this article, Flogas, cover the debate:

Construction businesses have a great responsibility not only to ensure that their sites and offices are environmentally friendly, but that the buildings that they create are also sustainable and have a reduced carbon footprint. This article will explore how construction businesses can use more eco-friendly methods and the best ways to begin to do this.

1. Use Efficient Waste Disposal Methods

One of the most significant problems when it comes to construction businesses and their impact on the environment is their waste disposal. Many construction businesses use toxic materials which have a negative impact on the environment if they are not disposed of using the right method. Therefore, construction businesses should look at reducing their carbon footprint through implementing practices such as recycling and efficient waste disposal schemes. At expert companies such as Axil Integrated Services, their total waste managementcan help you to limit the waste that you take to the landfill through their specialist advice team, who can help you to train staff about eco-friendly methods, reduce movements at your site, and introduce effective segregation of recycling materials.

In November 2017, a magnitude 5.5 earthquake shook Pohang, South Korea, and the researchers blamed the development of enhanced geothermal project for it.

The main working principle of enhanced geothermal revolves around creating a network of fractures in hot rock that is otherwise too impermeable for water to flow through.You pump cold water down one, the Earth warms it up, and you extract hot water at the other end.

The problem lies in the fact that pumping up the Earth with high pressure can lead to earthquakes as this was the case in Pohang.
