Hydropower is the most efficient way to generate electricity, convert as much as 90% of the available energy into electricity. The best fossil fuel plants are only about 50% efficient. In the U.S., hydropower is produced for an average of 0.85 cents per kilowatt-hour (kwh), is about 50% the cost of nuclear, 40% the cost of fossil fuel, and 25% the cost of using natural gas. Information of solar energy: Revolution has started Real Cost in different country (Refer to the Giles Parkinson) Deutsche notes that total module costs of leading Chinese solar companies have decreased from around $1.31 a watt in 2011 to around $0.50/W in 2014. It says this was primarily due to the reduction in processing costs, the fall in polysilicon costs and improvement in conversion efficiencies. It sees a precedent for this in the oldest major solar market in the world Germany. Costs

today are well below costs in the United States and other less mature markets, and total installed costs have declined around 40 per cent over the last 3 years in the country. Importance factor: Vietnams Require of Electricity Energy Refer to EVN, Thy in Vit Nam hon thnh s mnh lch s published on 26/12/2014: Electricity Energy was produced about 128 billion kWh (in 2013) & 141 billion kWh (in 2014) Refer to EVN, Pht trin thy in bn vng Vit Nam published on 23/07/2014: Electricity is increasing 7% per year (2010-2020) and 5% after this period.

Maximum limited energy from hydro-power will be 75.3 kWh in end of 2017. EVN has imported 711Million kWh of Hydro-power from China in first 6 months of 2015 (Refer to EVN website, EVN ang gim dn lng in nhp khu t Trung Quc published on 08/09/2015) Importance factor: Low costs of Hydro-Power? It is not really cheap if price including the cost from the evidences: - Cost of rebuild and deaths of people from accidents of dam collapse and water release from dam with bad management. - Mainstream Hydropower may impact: Flow regime; transport of sediment and nutrients; biodiversity; water quality; fisheries; navigation; and related socio-economic issues needed studied(refer to Mekong Delta Study on the progress, in MRCs report in 2015) Importance factor: Increasing imported electricity energy? National economic develop will depend and is controlled by supplying countries. Due to profit, more hydro-power stations will be built by neighbour countries and impact Flow regime; transport of sediment and nutrients; biodiversity; water quality; fisheries; navigation; and related socio-economic issues needed studied(refer to Mekong Delta Study on the progress, in MRCs report in 2015) * People life gets risky from Hydro-power dam collapse. Ex. Flood in Brisbane in

11/01/2011 Importance factor: Develop Fossil Fuel Power? Fossil fuels release CO2, NO2, SO2 & CO etc. when burnt that can have severe consequences on the habitats: 1. Environmental Hazards 2. Rising Prices 3. Acid Rain 4. Effect on Human Health 5. Non-Renewable 6. Impact on Aquatic Life by Oil Spill 7.

Steel & Wood (Bamboo) Frame & cost A combination of steel and cheap local treated wood to minimise the low cost but good quality for long term (more than 20 years). Bamboo can be

considered in research for later improvement. Photo for example Roof will be designed to install solar panels.

Contact to related organisations to obtain clear and accurate data for project recalculate in request of commission by the Government and advice for finance source. Contact to a suitable contractor to build a panel manufactory of 1.6m/year Establish

Club of Dr. Engineering: Duty: Training involving students to detail design of warm houses including panel assembly, infrastructure and house building techniques. Establish the link between university research centres, Dr. Engineering Club and private companies: Duty: Study equipment and process to produce solar generator kits as cheap as possible. Develop the cheap plaster-like wall and frame. Electrical Research (Universit y) Electrical Equipment Manufactor y Electricit y Network Solar Panel Manufactor y

Request domestic electrical supplier for 2000 inverters of 5kW.

Construct a village of 1000 houses which designed by Dr. engineering Club and built by training students and workers. Recalculate to evaluate the accuracy of proposal project. Establish Research and development team (between the university and companies) to develop the best and cheap products. Plan to build up panel manufactory of 1.6mil/year (10 total) Step 3: Build up manufactories and working teams to reach target of 16mil. Panels/year Build up panel manufactory of 1.6mil/year and keep doing to reach 10 total. Design and construct many villages in different locations with average number reaching to 180000 house per year. Installing the remain panels (50% of produced) on existing houses with a contracting to house owners. Research & Development keeps complete process to use bamboo instead of wood and steel as much as possible. Step 4: Marketing and Export Cheap Building Technology Study marketing for export cheap building technology to neighbour countries such as Lao, Cambodia, Philippine and Myanmar. How does a Non-Profit Dr. Engineering Club contribute?

Support university students to practice & experiences Students can earn some money from practice work from industry to support their study Experienced leaders can help students to work for member industries with low fee Member industries or governments can order some works like research, design or development with low cost. Note: club only charges little cost for output results as win and win Some examples of the works the club can do Design house for low income people Design and develop the existing machines in some industries. Manual to train new workers how to build the house using this method of building Can study and design away local street flood with low cost Can research a computational model to predict the flooded location from weather or collapsed dams. Conclusion:

This is proposal project to help Vietnam can produce green power for a future developing economic. Help the dream of low income people to own a quality house Create jobs for people Support students to catch up real modern industrial works. Contribute national industries and society develop the quality works with low cost using
