One of the reasons of development of air pollution is the production in each industry that continues to work every day. Work is relentlessly driven by human needs increase along with significant population growth. If the industry is engaged in the production of goods alone increased rapidly, how the industry is moving in the field of food are needed every day for the body? Of course, be dozens of time.
One significant example in this regard is the tea industry in the eastern African region that employs more than one million people, has long been a source of income of the surrounding population. In addition, more than four million people are supported through the tea industry. Kenya, Burundi, Rwanda, Malawi, Uganda, Tanzania, and Zimbabwe together produce 28% of the world’s supply of tea.
Unfortunately the industry is not supported by good energy management. This is a matter of considerable attention because of the current state of the world affect energy use and greater utilization of alternative energy that comes with various types.
In the process, the tea industry needs 8 kWh of energy to produce one kilogram of tea that is ready for consumption. This amount is greater than the energy required to process steel of 6.3 kWh. While in Africa, energy is not only expensive but also not reliable. Strength power supplies up and down that are harmful to compel the production process of tea industry using diesel engines as a source of backup power. As we all know that diesel engines produce the amount of carbon emissions and very much dark.
However, the tea plantations are located in the mountains – an area with high annual rainfall and river flows throughout the year – making the area ideal to be the location of hydroelectric power and is expected to be a way out for the transfer of the use of diesel engines with petroleum fuels.
With the support of the project Greening the Tea Industry and funding from the Global Environment Facility (GEF), a feasibility study for the eight hydroelectric projects has been completed and is expected to more than six hydropower plants will be built as a small pilot project.
If later there is excess supply, power will be used to meet the needs of the surrounding villages that have no electricity grid. So that no energy is wasted without being used. Plan, during the next 20 years, the project is expected to invest in a number of hydropower on a small scale with a capacity of 82 MW.
Feasibility studies for 19 projects in Malawi, Kenya, Tanzania, Rwanda, and Uganda found, required additional investment of up to U.S. $ 22 million to establish six pilot projects. Micro-hydro power plant is now also being built in several key areas in Kenya and Rwanda. Another plan to build new power plants is also being finalized in Tanzania and Malawi.
UNEP also supports the implementation of tariff policies (feed-in tariffs) to encourage the application of renewable energy sources other in Kenya and Tanzania.
By using this policy, the national power grid is obliged to buy electricity from any supplier of green energy and help promote investment hydroelectric power in the region. And with the expected reactivation of this power plant, could help more than one million farmers and their needs.
