Energy Saving Tips

energy saving tips

Energy saving tips are always a good idea as it can help you to be more energy efficient reducing your energy bills. But energy saving isn’t about not turning on your heating, or cooling systems, its about using what you have in more efficient ways. Simple energy saving tips such as turn off lights not being used, Replace conventional light bulbs with efficient light bulbs, use the winter sunlight to heat your home and keep it out in the summer, clean or replace old filters and insulation, all are simple can do energy saving tips to help you reduce your energy costs

Energy Conservation

energy conservation

Energy Conservation is about reducing your homes energy usage by designing a more energy-efficient building. Lowering a buildings utility bills not only saves you money but benefits the environment, and makes for a more comfortable home. Energy efficient and renewable energy components such as upgrading lighting circuits and fixtures to LED, strategic insulation and glazing to reduce your homes peak heating and cooling demands, or the installtion of solar photovoltaic panels, all add towards a more energy efficient home

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.

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

Renewable Energy A Sustainable Energy Source

types of alternative energy

Renewable energy sources are vast in scope and type from solar thermal and photovoltaic energy, hydro (tide, wave and ocean energy), wind power, geothermal energy as well as all forms of biomass products from biological wastes to liquid biofuels. Renewable sources of energy for home cooking, heating and transportation are becoming more widespread as our reliance on more traditional fossil fuels reduces. Renewable energy as a sustainable energy resource reduces greenhouse gas emissions with the development of energy from renewable sources increasing energy efficiency

Non-renewable Energy Sources

Nonrenewable energy sources are those which took thousands of years to form and exist in fixed amounts in the Earth so cannot be replaced during the time of a humans life span. Norenewable need to be conserved before they become depleted. Fossil fuels in the form of coal, natural gas, and oil as well as fossilized wood, charcoal, and peat are all regarded as nonrenewable energy sources. Burning these fossil fuels accelerates global warming due to more greenhouse emissions and pollution released into the atmosphere

Renewable Energy Sources

types of alternative energy

Renewable energy sources of energy are abundantly available around the world but are also insufficiently exploited to reduce our dependancy on harmful fossil fuels and increase energy capacity. Renewable energy technologies which harness the potential of the sun, sea, waves and thermal heat have the benefits of reducing the environmental and climate impact on life while at the same time providing a cost effective means of powering our homes and vehicles. The development of high-efficiency solar cells and modules, geothermal heat pumps and marine energy devices create an environment based on renewable sources that provide flexibility to the energy system



Vermicomposting composting uses red earthworms and their by-products to produce a rich fine granular organic manure to enrich the soil improving the health of plants and flowers enormously, and today is a major part of organic gardening. Composting with earthworms is an excellent technique for making use of household kitchen scraps and garden rubbish that would have previously gone to landfill. Vermicomposting has a good potential to turn unwanted waste material into a valuable soil amendment all year round.

Anaerobic Composting

anaerobic compost

Anaerobic composting uses bacterial micro-organism called anaerobes to produce a humus and nutrient rich organic matter in the absence of oxygen using fermentation, similar to the fermentation processes which occur naturally in bogs, swamps, marshes and other such wetlands that produce peat compost and moss. Wet Anaerobic Composting converts liquid organic wastes into a rich source of renewable energy in the form of Biogas.
