Wind Power

The power of wind is a renewable energy source that will never run out, emits no greenhouse gases or other pollution, and could be a cost-effective alternative to fossil fuel energy and nuclear power. That means that wind power, along with other sustainable forms of energy generation, will be part of the solution to global… Continue reading Wind Power

Solar Power

The sun provides all of the energy for life on Earth, powering plants, animals and human activity. Solar power systems allow us to generate electricity from sunlight. This can be direct conversion through photovoltaics or indirect through mirror arrays. Photovoltaics are small cells that convert solar radiation into a stream of charged electrons. These photovoltaic… Continue reading Solar Power

Sequestration

Sequestration is the process of pulling carbon out of the atmosphere and storing it somewhere safe where it will not escape and contribute to climate change. Reducing the amount of carbon currently in the atmosphere is a necessary part of stopping climate change. Major changes need to happen to stop further emissions from contributing factors… Continue reading Sequestration

Nuclear Power

Nuclear power plants generate electricity in almost the same way as traditional fossil fuel-based power plants. Both heat water into steam, which powers a generator that produces energy from charged electrons. It is the method of heating the water that is the major difference. Fossil fuel plants burn coal, oil or gas to make heat,… Continue reading Nuclear Power

Green Infrastructure

‘Green infrastructure’ means sustainable versions of the fundamental facilities that serve society. Schools, hospitals, energy generation, transportation and communication systems are all part of the infrastructure that supports local, national and global economies and societies. Making these systems low-carbon intensive would go a long way to stopping climate change. Currently, buildings use about half of… Continue reading Green Infrastructure

Green Cities

Imagine living in a real jungle, not a concrete one. You could look out of your office window and see buildings covered in solar panels, vertical gardens ascending the walls, dropping fruit and herbs down for your lunchbreak. Enter the world of green cities, where entire towns take action to make their communities more sustainable… Continue reading Green Cities

Ethanol

Ethanol is made by fermenting plant sugars or the by-products of petroleum processing. Traditionally used as both an alcohol and a fuel for heat and light, today ethanol is employed as a transport fuel. Because it can be derived from renewable resources such as plant matter and organic waste, ethanol can replace the fossil fuels… Continue reading Ethanol

Biochar

Biochar is a form of charcoal that is made by burning organic matter in a combustion chamber with limited oxygen, a technique known as ‘pyrolysis’. Pyrolysis makes the wood, manure, or crop waste used in the process more structurally stable, making biochar difficult to break down. This means that biochar can remain in the same… Continue reading Biochar
