One question that comes up often with our homeowners is how to track how much energy is being produced.  The solution to this is the monitoring systems.  Currently Kiosk uses two different types of monitoring systems, depending on the type of system.

1. Microinverter systems have monitoring embedded into each microinverter, which are attached to each panel.  They allow for per panel monitoring.  You monitor the system by going onto the Enphase website and putting in your login and password.  This is what the Enphase portal looks like:

2. Tigo boxes are designed for systems that use string inverters.  The Tigos are attached to every panel, to monitor the production output and optimize production based on light conditions.  You monitor the system by logging into the Tigo website and putting in your login and password.  This is what the Tigo portal looks like:

Mahasiswa Departermen Teknik Kimia Universitas Indonesia punya cara unik dalam mempromosikan penggunaan energi terbaharukan di lingkungan kampusnya. Mereka menginstalasi Solar Panel diatap gedung departermen mereka yang output listriknya digunakan sebagai kebutuhan charging laptop dan handphone di saung tempat mahasiswa biasa berkumpul. Proyek ini adalah bagian dari tugas mata kuliah Energi Berkelanjutan yang merupakan mata kuliah pilihan di Jurusan Teknik Kimia. “Proyek ini merupakan action nyata pengimplementasian keberlanjutan dan bauran energi ketika kita seringkali hanya mewacanakan isu-isu tersebut” ujar Prof. Dr. Ir. Widodo Wahyu Purwanto, DEA sebagai pembimbing mata kuliah Energi Berkelanjutan tersebut.

Solar panel yang dipasang memiliki total daya 815 Watt dengan masa pakai hingga 25-30 tahun. Instalasi solar panel tersebut mampu menghasilkan energi hingga 1.335 kWh pertahun yang artinya dapat mereduksi gas karbondioksida…

I often look at the CV’s of researchers whose careers I admire to get a sense of their trajectory, and to build a rough road map of goals and objectives. How many papers do I want to put out in order to be as competitive as possible for a particular kind of job? How much grant money does the average faculty member generally pull in before tenure? I generally think it’s better to compete with yourself rather than with others, and I would prefer to be driven by good questions and careful science than aggressive CV-building. But I do find it useful to see the range of development of scientists through time (especially in terms of research themes and the kinds of papers published at different career stages).

‘Arctic wildcard stacking the deck in favor of more severe winter outbreaks‘

By Summit Voice

SUMMIT COUNTY — Evidence continues to mount that melting Arctic ice is having a significant effect in the mid-latitudes, where most people live, and it’s not something that’s going to take decades to develop.

Instead, researchers say, the warming of the high latitudes has decreased a historic pressure gradient at the boundary of the high- and mid latitudes. Basically, the pressure difference has decreased, and that is having a fundamental effect on the way the jet stream moves from west to east in the northern hemisphere.

Comunicado de Prensa

Varias organizaciones políticas y comunitarias denunciaron en la tarde de hoy miércoles lo que consideran ha sido un proceso judicial injusto y atropellado por parte del juez Javier Varela Rivera del Centro Judicial de Ponce contra las 6 personas arrestadas el pasado 15 de diciembre en el Valle de Santa Isabel, donde la empresa Pattern Energy instala 44 molinos de viento.

Entre las denuncias expresadas, plantearon que el juez Varela Rivera violentó el derecho de los imputados a un proceso judicial rápido. Como cuestión de hecho, la vista preliminar en su fondo comenzó el pasado 31 de mayo, 110 días después de concluida la vista de causa. Las reglas de procedimiento criminal establecen que la vista preliminar tiene que verse en un término no mayor de 60 días.

Además de no garantizar el derecho a un proceso judicial rápido, el juez Varela Rivera adjudicó la culpabilidad de…

Astonishing algae bloom found in Arctic Clipped from: http://www.tgdaily.com/sustainability-features/63906-astonishing-algae-bloom-found-in-arctic

by Kate Taylor

NASA scientists say they’ve made a discovery in the Arctic Ocean ‘as dramatic and unexpected as finding a rainforest in the middle of a desert’.

When its Icescape expedition punched through three-foot thick sea ice, the team found waters richer in the microscopic marine plants known as phytoplankton than any other ocean region on Earth.

The expedition explored Arctic waters in the Beaufort and Chukchi seas along Alaska’s western and northern coasts onboard a US Coast Guard icebreaker.

"Part of NASA’s mission is pioneering scientific discovery, and this is like finding the Amazon rainforest in the middle of the Mojave Desert," says Paula Bontempi, NASA’s ocean biology and biogeochemistry program manager in Washington.

"We embarked on Icescape to validate our satellite ocean-observing data in an area of the Earth that is very difficult to…
