Alternative Energy Tutorials on Solar Power

Solar Irradiance

Solar Irradiance

Solar Irradiance describes the total amount of sunlight per square meter that is available at any particular location on the Earth’s surface and is a major part in estimating the solar irradiation at a particular point required to design a sustainable energy system using photovoltaic solar panels. The performance of a solar photovoltaic panel depends on many factors, but the amount of solar irradiance in peak sun-hours during the day that the solar panels receive during the day is of major importance

Low Pressure Micro Hydro Power

Micro Hydro Weir

Low pressure micro hydro power scheme is another type of hydropower technology which uses low-pressure, low-head turbines to generate electricity without the need for dams or water impoundment. Micro hydro power is another renewable energy source with a low environmental impact and having several advantages over the use of fossil fuels as it is a non-polluting, renewable resource causing minimal environmental disruption to both the river and the native ecology.

Tidal Power

tidal power

Tidal Power takes advantage of the kinetic energy stored in the movement of the incoming and outgoing tides using tidal stream devices, as well as the daily differences between the high tide and low tide at a given location using tidal barages. Tidal power is a non-polluting technology with a great potential to generate large amounts of electrical energy as the moving sea water drives underwater turbines with current technologies based around tidal range and tidal stream devices.

Efficiency of Biomass Energy

efficiency of biomass energy

The efficiency of biomass energy depends on how effectively biomass resources can be converted into electrical power, heat and fuels using a variety of new techologies and traditional methods. Biomass energy crops are now being grown in vast quantities to produce modern forms of energy such as biofuels for transport, pellets for electricity generation as well as a wide diversity of bio-chemicals and bio-lubricants making biomass a truely versatile fuel.

Wind Power and the Environment

wind power environment

Wind power and the environment continues to be a discusion as we use the renewable energy sources available within the environment to power our lives. While wind power is a clean, sustainable and accepted alternative to burning fossil fuels, the environmental imapact of wind power on wildlife and their natural habitats must be taken into consideration when siting a new wind farm. Wind farms built for the production of electricity have the potential to impact the natural and urban environment affecting birds, bats and other fauna and flora at a specific site

Rainwater Harvesting

rainwater harvesting

Rainwater harvesting is a sustainable strategy that saves and reuses rainwater for use in the garden or home reducing the demand on clean drinking water. Rainwater and storm water runoff from roofs or impermeable paved areas is collected in rainwater tanks or containers for consumption in the garden. Rainwater harvesting is dependent on both run-off area and the environmental weather conditions of the collected rain water but rainwater harvesting continues to be a sustainable solution for most gardeners.

Sustainable Development

sustainable development

Sustainable development is about management and development of our energy needs so that they meet the requirements of the present day without compromising the ability of our future generations to meet theirs. The scarcity of clean drinking water, energy, and arable land for food crops all have an impact on climate change as the dependency on fossil fuels increases. Sustainable consumption and production is about managing the worlds resources in a controlled and cleaner way.

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

Sustainable Food Production

sustainable food

Sustainable food and agricultural systems grow and ensures food safety and nutrition for all in such a way that the economic, social and environmental conditions used to produce the food is not compromised for future generations. Creating a sustainable food future to nutritiously feed an ever growing world population in ways that can help against food poverty, meet climate change goals while reducing the loss of habitat, freshwater depletion and pollution, and other environmental impacts of farming is a major goal of sustainable food production
