Solar Gardens

Solar gardens use the sun’s energy to power pumps, fountains and ornamental lights throughout the year. We all like to see our gardens full of plants and flowers during the day, but also illuminated at night aswell. A solar powered garden uses solar photovoltaic panels to turn the suns energy into electricity and then uses this energy to power elements of their garden, whether its lighting, fountains or the occasional garden gnome. Using the free solar energy in the garden a great way of going green thereby helping to save the planet, and is a safer, easier and cheaper way than installing mains powered electrical equipment around your garden

Solid Waste

solid waste

Solid waste as a renewable source of energy is a way of reducing the dependency on conventional fossil fuels for energy generation. Waste-to-energy technologies help reduce greenhouse gas emissions, environment pollution, fossil fuel use, and unnecessary landfill dumping. Energy generation from waste materials reduces pollution caused by the burning of coal and oil based fossil fuels, and the land which would have otherwise been used for landfill purposes can be used for many other useful and green purposes

Sustainable Agriculture

Sustainable agriculture is the organic production of food to feed the world’s population without destroying the land. Conventional agriculture with its use of fertilisers, high water consumption and poor soil management is not sustainable. There are many aspects to sustainable agriculture from improved soil amanagement methods were the soil is much less susceptible to wind and water erosion, to crop rotation and cultivation techniques that keep disease, pests and weeds to a minimum

Collecting Solar Power More Effectively

roof solar panels

Solar panels produce electrical energy using photovoltaic cells.These photovoltaic or PV cells are made of semiconductor silicon based materials similar to those found in modern day computer chips. When the suns rays hit these silicon cells, it knocks electrons loose from their atoms to generate electricity as they flow through the cell. By improving the way in which the suns rays are absorbed by a PV cell using tracking, collectors or new materials solar panels are able to collect solar power more effectively improving a systems performance.

Movements of Waves

ocean wave energy

The movements of waves in the oceans is energy and not the water itself which moves across the oceans surface. The water in the worlds seas and oceans is dynamic. The horizontal movement of water around the planet we call currents and waves, while the vertical rise and fall motion of the water we call tides. Its the winds blowing across the waters surface which causes the movement of waves to finally release their stored energy as they crash on the shoreline

Freshwater Production

water

Freshwater production technologies can help sustain all the life here on Earth with access to clean drinkable freshwater supplies being a major human need. Water is the most essential ingredient for our bodies so having access to fresh clean drinking water is vital. Desalination plants and large scale solar stills are being installed and used all over the world in order to satisfy the freshwater demand in countries where access to fresh clean drinking water can sometimes be a challenge

Hydrogen Energy

hydrogen energy gas

Hydrogen energy from a renewable energy perspective is a low-carbon energy supply we can use to power our homes and cars. Green hydrogen is a clean energy source which can play an important role in reducing the global requirements of fossil fuels. The use of hydrogen energy can provide the bridge between the variable output from solar photovoltaics and wind turbines as well as becoming a lowest-cost option for storing large quantities of electrical energy. Hydrogen and hydrogen-based transportation fuels can help transport renewable energy sources over longer distances

Solar Cooling

solar cooling

Solar cooling removes the need for refrigeration and air conditioning systems which can dramaticly increase electricity consumption and therefore greenhouse gas emissions. Solar cooling systems can save energy in comparison to conventional cooling technologies as their main design and operation uses solar energy. The advantage here is that any air conditioning and cooling requirements is at its highest when the solar irradiation is abundantly available so the cooling demand produced from solar energy is immediately used

Hydroelectricity

hydroelectric power

Hydroelectricity uses the force of falling water from large reservoirs or the flowing water of rivers, streams and waterfalls to generate electrical energy using water turbines. Hydroelectricity genetation schemes are common throughout the world and are a well established clean energy source with pumped hydro storage and run-of-river schemes used to generate electricity. Being a flexible, readily available and zero emissions source of renewable energy, hydro power will continue to play a vital role in our clean energy future

Pico Solar Systems

Pico solar systems use small scale photovoltaic panels for lighting and battery charging applications. There are still many people around the world who have no access to an electricity grid connection or require a portable energy source for camping or RV’s so pico solar systems can help in provide the essential energy required to fill this gap. Pico solar systems of only a few watts have experienced significant development in the past few years, combining very efficient LED bulbs with sophisticated charge controllers and energy efficient storage batteries providing power for lighting, phone charging or powering a radio, etc.
