In addition to strengthening R&D of technologies for CO2 emissions reduction and cleaner emissions from products, Honda has been hard at work developing energy-production technologies. One of the products featuring such technologies is the household gas engine cogeneration unit, which is at the core of a household cogeneration system that uses a gas engine to produce electricity while at the same time recovering the exhaust heat to supply hot water. In 2011, Honda fully upgraded its gas engine cogeneration unit to further increase thermal efficiency and fuel efficiency and to make it more compact, and introduced it in Germany and Japan. Honda also plans to introduce a new version of its copper, indium, gallium, and selenium (CIGS) thin-film solar cell in Japan. These solar cells, developed independently by Honda, will achieve the world's highest-level of module conversion efficiency among CIGS solar cells currently on the market. Moreover, to realize a goal of managing in-house generation and consumption of the energy required for a home, such as heat and electricity, Honda is conducting demonstration testing using a house that features the Honda Smart Home System (HSHS), which comprehensively controls in-house energy supply and demand.
Honda's solar cell is a thin membrane made from a non-silicon compound of copper, indium, gallium, and selenium (CIGS). Compared with a silicon-type cell, this solar cell is environmentally responsible due to greatly reduced energy consumption in the production process.

As the leading innovator of 4-stroke outboard engines, Honda offers a wide array of products designed for outstanding levels of dynamic and environmental performance. In 2011, Honda introduced the BF250, its flagship outboard engine model, to extend the lineup from 2 hp to 250 hp.

Honda general-purpose engines have demonstrated excellent performance in fuel efficiency, power output, reduced noise and durability. Especially popular are the GX series engines, now the best-selling 4-stroke general-purpose engine series with cumulative production exceeding 40 million units (as of January 2012, based on Honda's internal data).

Tillers were Honda's first power product and the first of many complete units. Today, a full range of models is available for almost any situation.

Enjoying an excellent reputation for their high reliability and ease of operation, Honda's extensive lineup of generators is used to meet a diverse range of needs, such as outdoor recreation or as an emergency power source during a power outage.

Honda has developed the technology for engines powered by handy home-use butane canisters. The current lineup of Honda products adopting this technology includes the Pianta mini-tiller and the Enepo electric generator, which have enjoyed widespread consumer support.
