Jakarta Provincial Government is continuously conducting various efforts to reduce gas emission up to 30 percent in 2030. One of them is replacing some lamps on street light (PJU) with energy saving lamps. Even, Jakarta Industry and Energy Department also does the same thing that is by installing energy saving lamps in type of light emitting diode (LED) around non-toll flyover (JLNT).
Jakarta Industry and Energy Department, Andi Baso stated to save energy, his department uses the lamp in type of LED to be installed on two JLNTs, such as Kampungmelayu-Tanahabang and Antasari-Blok M. Later on, 3,090 lamps will be installed in those JLNTs.
LED is able to save energy up to 50 percent compared to street light. In details, street light only has a capacity of 400 watts, so LED only 200 watts. “LED can able to reduce greenhouse gas about 0.891 of greenhouse gas production, which not uses energy saving lamps,” he expressed at Jakarta City Hall, Monday.
Andi said, 222,342 street lights in Jakarta needs power about 45-50 mega watts per day. Meanwhile, 92 out of them are using solar-cell powered light which spread in five areas in Jakarta. Rp 3 trillion is needed to replace street lights with energy saving lamps. “In fact, one solar-cell lamp is sold Rp 30 million,” explained.
Next year, his department will spend budget Rp 351 billion to replace a portion of street lights with LED. “Yet, we’ll discuss this plan first to Jakarta Parliament (DPRD). If it is agreed, we will soon install the lamp,” he told.
Chief of Indonesian Democratic Party of Struggle (PDI-P) for Jakarta DPRD, Syahrial, acknowledged he agreed with Jakarta Energy and Industry Department’s plan. Due to the high budget, the installation is hoped can be installed gradually. “The installation of LED lamps is right decision due to it can save the energy,” he argued.
Replacing an old window with a new energy-efficient unit can make a remarkable improvement to a room, not to mention lower energy bills. An awning window provides light and opens outward to catch the breeze, making it a good choice in any room. The sash closes tightly against the frame, making it better than a traditional double-hung unit at stopping air infiltration.
A single large awning window is often used in a kitchen over a sink; pairs of them often flank other windows or are arranged together over large patio doors. When you remodel a basement, replacing an old awning window goes a long way toward making the space down under more livable and attractive.
A window contractor will charge $325 to install a 3-foot by 4-foot awning window, which includes the labor and material. If you have carpentry skills and tools, you can do the job for $190, the cost of the window, and pocket a 42 percent saving. The cost will be higher if new trim on the inside is needed and the exterior siding needs to be replaced around the new window.
Plan the project so you can remove the old window and immediately install the replacement; otherwise, the gaping hole in the wall may invite birds or animals to come inside.
