Eco House


We have been learning about living sustainably one of our ideas for doing this is to live in Eco houses. My Eco house will have power generated by wind turbines and water heating creating by harnessing the energy created by the sun through my solar panels. Also my house will have insulation to keep the warm in and so i don't have to keep turning the heater on and save energy.I'm going to get Photovoltaic bars so i can produce electricity from sunlight.For my water i will have a water butt to collect water from rain gutters,rooftops and rain.To get heat i will use a ground heat pump to get heat from to the ground.For my windows i will have double glazed windows to keep the heat from escaping so i can use less heat.In conclusion in my house i will have solar panels to collect energy from the sun.Special thanks to Mystery Man for helping me understand these things.Click here for his blog

Sustainability

Sustainability, in general terms, is the ability to maintain balance of a certain process or state in any system. It is now most frequently used in connection with biological and human systems. In an ecological context, sustainability can be defined as the ability of an ecosystem to maintain ecological processes, functions, biodiversity and productivity into the future.[1]

Sustainability has become a complex term that can be applied to almost every system on Earth, particularly the many different levels of biological organization, such as; wetlands, prairies and forests[2] and is expressed in human organization concepts, such as; eco-municipalities, sustainable cities, and human activities and disciplines, such as; sustainable agriculture, sustainable architecture and renewable energy.[3]

For humans to live sustainably, the Earth's resources must be used at a rate at which they can be replenished. However, there is now clear scientific evidence that humanity is living unsustainably, and that an unprecedented collective effort is needed to return human use of natural resources to within sustainable limits.[4][5]

Since the 1980s, the idea of human sustainability has become increasingly associated with the integration of economic, social and environmental spheres. In 1989, the World Commission on Environment and Development (Brundtland Commission) articulated what has now become a widely accepted definition of sustainability: "[to meet] the needs of the present without compromising the ability of future generations to meet their own needs.”[6]
