Electricity crisis and the more expensive encourage all parties to begin to get used to use environmentally friendly alternative energy. Though not much developed, residents continue to look for electric power (if possible) a simple and inexpensive, among them:

• electricity through the utilization efficiency of energy saving lamps and natural light is considered as the best solution for dealing with the current electricity crisis.
• 19 percent of electricity consumption in office buildings in the world comes from lighting. Therefore, this lighting efficiency will have a big impact for the reduction of carbon emissions generated from electricity production process.
• Savings that can be achieved by reducing the frequency of electric power and lighting sources with a stun-efficient lighting technology. Utilization of such lamps can reduce electricity consumption assessed from the lighting sector, up 40 percent.
• Right now the LED light technology into the most appropriate solution for this type of lamp light intensity had a large but low power consumption. In addition, it should also be noted about the house lights. “Design right lamp holder can maximize the spread of light so that no deployment in vain,”
• Efficiency is increasing the maximum power if the consumer is to combine the use of artificial light with natural light from the sun.
• A combination of energy efficient technology utilization of artificial and natural light can cut electricity consumption by 50 percent. “We can take advantage of this natural light as much as possible. For office buildings, a combination of 30 percent and 70 percent natural light artificial light has been very good,”
• Trends in usage of energy efficient lighting and natural light. Users are not only large shops and offices, but also the public sector
• Use of solar cell panels on the roof of the building to heat water and a few point lights.
• In coastal areas, carried out the development of windmills to supply electricity.
• Biogas has also been ogled to illuminate the lights or cooking. Alternative energy development environmentally friendly house electricity should continue to be done so that the house does not depend much on electricity supply in the future.
• Availability of KDH 30 percent more houses and provide opportunities for residents can breathe easier. Green space developed into a park with the park concept based on the needs of residents, such as parks therapies / reflection / relaxation, water garden, flower garden, or in accordance with the architecture of tropical gardens, minimalist garden, Japanese garden and Mediterranean garden.
• This beautiful park ecological contribution to the city as a private green open space part of the green open spaces of the city. Residents are entitled to incentives such as tax reduction, cutting the cost of electricity, telephone and other facilities, from the government as the government’s appreciation for the participation of citizens in the increase of urban green.
• The architects began diligently to build a green roof (green roof, roof garden) as an effort to replace the land (green) that is built up. In large cities and densely crowded, the presence of green roofs cool tub oasis amidst the concrete jungle city. Not enough, the walls of the house also becomes a wall clad in ivy green (green wall).
• The buildings are covered with plants proved to affect the micro climate surrounding environment. The heat down. Parks became a natural roof insulation. Solar radiation absorbed by plants. Gas processing plant pollutants into oxygen. Rainwater can be collected, absorbed, and then flowed into the pipe and to sink into the recharge wells.
