Using sustainable water sources for water control and energy self-sufficiency, and controlling climate control

Global warming has melted the ice caps and glaciers, increasing the amount of ocean water and raising ocean levels. This has led to large typhoons, tornadoes, heavy rainfall, thunderstorms, and other increases in fluid energy.
Once ice has melted, there are no artificial ways of ever restoring the ice caps or glaciers. However, one idea to combat this is for each country to store water from rainfall underground in mountainous regions thereby controlling fluid energy and reducing floods by letting water flow in controlled amounts from the mountains to generate power in a continuous process that then returns the water to the ocean. This method would store excess water that comes from melting and reduce fluid energy that results in major typhoons, tornadoes, heavy rainfall, and thunderstorms through water control. At the same time, it can be used to generate power as it flows back to the ocean.

Sekisui House’s Decarbonisation Business – Changing the Future for a Happy Life

In 2008 Sekisui House Ltd. announced the Decarbonisation Declaration and declared the intention to eliminate CO2 emissions from the entire lifecycle of their houses by 2050. In order to achieve this, in 2009 Sekisui House introduced the Green First eco-friendly homes to reduce CO2 by 50% or more and protect our precious green Earth. In 2013 Sekisui House released Green First ZERO, the net Zero Energy Housing (ZEH) model. By 2017, ZEH accounted for 76% (35,881) of their detached houses, making them the top seller of ZEH in the world. In real terms, Sekisui House achieved a CO2 reduction rate of 100,000 tons from 1990 figures. Sekisui House joined the COP21 Global Alliance for Buildings and Construction in 2015, and joined RE100 and the SBT Initiative in 2017 and 2018 respectively, as Sekisui House accelerates their efforts to achieve a carbon-neutral society.

Using geothermal technology to create a decarbonized society

We barely use geothermal energy, which has very high energy-saving qualities. We researched and developed new geothermal technologies and successfully created economically feasible geothermal energy. This technology can reduce energy consumption for heating by more than 50%. The costs of constructing power generation facilities will also be greatly reduced, making progress towards a decarbonized society. Furthermore, geothermal technology is extremely low-tech, so it can be applied in emerging economies for use in ironworks factories, and waterworks companies. Rather than focusing solely on developed nations, geothermal technology can be applied at low risk and low cost in emerging nations, thereby contributing to economic expansion.
